Description: This vintage Fisher 500C vaccum tube stereo receiver comes form a time when equipment was manufactured in the USA and to highest standards of quality. It is tested in fully working condition and all in it appears orgiginal. The 500C features 7591 output tubes, used in push pull configuration and providse about 35 W RMS per channel. Output impedance of the amplifier, is selectable between 4, 8 and 16 Ohms. The pre- and power amplifer can be separated and there are RCA jacks to use these circuits separately.
Features: Inputs: 2 Phono inputs (high and low); 1 AUX input, 2 Tape Inputs (heads, monitor) Outputs: tape recording outputs, center chanel oputput, screw terminals for 2 pairs of speakers, selector taps for output impedances of 4, 8, 16 Ohms. Front Panel Elements (Left to Right, top to bottom) Speaker selector switch, Stereo Indicator panel, tuning dial, radio signal strngth meter, tuning knob, separate controls for left and right chanels: Bass, Trebble; Ballance, Hi and Low filter switches, headphone jack (labeled as "EARPHONE"), MPX filter switch, tTape monitor switch, Input selector switch with: Tape heads, Phono mono, Phono stereo, FM AUTO (automatic stereo mono switching), FM stereo, FM Mono, AUX/Tape, Loudness switch (operated by it's own knob), Volume. .
Tubes: 4x 7591 (Output); 9 x 12AX7, 2 x 6AU6, 1 x 6K5, 1x 6HR6, 1 x 6GK5, 1 x ECC85.
Condition: Tested, fully working. Contacts, etc. cleaned. It fully works and sounds quite nice. Both channels deliver steady signals without distortion and clear highs. Both channels seem balanced with nice bass and highs. The tuner section fully works as well and receives even weak stations and the stereo decoder appears to work. All is in good working order. I did not find any intermittency after cleaning switches and controls. It works as it should be and already sounds great. Not to say that the unit could not benefit form going through it in depth to clean tube sockets etc. For long term reliability though ideally it should be re-worked in all aspects that are affected by aging, such as replacing capacitors and out of tolerance components. The unit is as shown and does not have a wooden case. This unit is ready to ship, fully tubed with all the original tubes it came in with. Physical Condition: No issues. No missing parts. No Damages, but unit will definitely benefit from physical cleaning.
Work performed to rework this unit: I have taken the time to power the unit up slowly with a variac to carefully condition the capacitors for use. I did a basic tune-up job: deoxydizing all controls and switches and some of the tube sockets.and have done a general contact cleaning job to go through controls, tube sockets and switches.

Detail: Question: "Is this Fisher 500C gold or silver colored?" Answer: The unit is brushed aluminum, meaning "silver", but may appear slightly yellow and could benefit from a cleaning. In order not to damage any of the printing, I left that all original to be processed by the buyer. The covers of the knobs, however, are brass (golden).
Question: "Are you saying it will need to be worked on asap or is it in operating cond. now?" Answer: The unit is currently in fully working condition, but with all equipment of that I age I would recommend to replace aged components for performance to specs and for long term reliability. Also: new capacitors will bring more detail and sparkle in sound.
Price: $449.00 (- As described - see section: "Condition" ), OR:
Fully refurbished, (replaces aged / out of tolerance components and upgrade aged capacitors with nice quality capacitors), and add a wooden case $900 to $1250

Description: This is a matching vaccum tube pre-amplifier / power amplifier set. However as applications for both units may varry, I offer also to sell them separately. LEAK was a British company, who manufactured pro-audio equipment for the broadcast industry, and these Hi-Fi stereo units were desinged and manufacturesd in Great Britain in the 50's. The dates of manufacture are: 1960 for the pre-amplifier and 1961 for Stereo 50 Power amplfier. These unis are completley overhauled with an in depth job and quality components: All capacitors in these uniits were replaced for decades of trouble free services to come. This is an exceptional value, as very time intensive, and aged compontents if left unattended, even in fully working vaccum tube equipment, very likely will cause problems.
The pre-amplifier is charakterized with two main features: wide control over the tonal qualities of the signal and the offering of several equalization curves in the pho pre-amplifier stage, to adhere to various vintage record standards.
The power amplifier is charakterized with above average outptu power with it's 50 W RMS of tube power per chanel , plus precision in sounds, as ultra linear circuitry is applied (similar circuits found in McIntosh tube amplifiers)
How do these sound? Vintage sound with a lot of warmth and detail with great dynamics and the feeling of power. Be impressed! More powerful than the average stereo tube amplifie. I have also original LEAK speakers that match this set quite well, which can be found HERE!
Detailed Features for the STEREO 50 power amplifier: This amplifier uses a pair of EL34 / 6CA7 output tubes, ultra linear outptu transformers and driver circuitry that is comprised of 3 12AX7 triodes per chanel. The amplifier provides regular RCA input jacks to be used with regular stereo equipment, but also provides a LEAK specific 8 pin jack to connect directly to the pre amplifier. This jack provides power to the pre-amplifier and received the audio signal from the pre-amplifier. Each of the output transforers provides 3 selectable outptu impedances: 4, 8, 16 Ohms. There is a power input jack, which includes a ground pin (power cable included). The unit also provides 2 AC power outlets which accept regular AC power plugs.
Tubes: 4x 6CA7 / EL34 / KT66 (Output); 5AR4 / GZ 81 Tube rectifier (Rectifier), 3 12AX7 pre-amp / driver tubes.
Detailed Features for the Varislope STEREO pre- amplifier: While this pre amplifier was originally designed to compliment power amplifiers, it's actual application today are much more than originally desinged for, including to be used as a vaccum tube Mirophone pre-amplifier, a tube phono pre-amplifier, or even a tube tone bank for recording studio applications. In my eyes the Varislope STEREO is a widely underrrated piece of gear and a great secret weapon to bring tube warmth to todays digital world, both for home and studio environments.
The unit has inputs for: Microphones, Magnetic tape heads (such as found in vintage open reel tape deck chassis - tube echo comes to mind), 2 Magnetic turntable cartridges, tuner and auxiliary. Each of the phono, tuner, aux inputs provides a gain swith that allows to select between HI and LOW. There is a pair or RCA recordign ouytputs. The front panel of this pre-amplifie roffers the folowing: (in the picture let to right, top to bottom): Input selector rotary switch with positions for: EXTRA, TUNER, Phono RIAA, Phono NARTB, Phono 78 OE, Phono 78 NE,
(The different phono equalisation other than RIAA are to address standards of records manufactures prior to 1955 - British and American - record collectors heaven!); The pre-amplfier provides a rotary switch for chanel selections. These options are provided: Reverse, Stereo, R, L, Mono (Perfect if using thsi unit to transfer vintage audio material!). There is a "Bass" control, a selector switch that selects between phono input 1 or 2; There is the dual layer filter switch: the inner ring gives 4 positions to adjust the slope of the filter, the outer ring provides 4 positions to adjust the filter frequency similar to that found in a parametric Equalizer. The switch right of the filter knobs switches a "rumble filter " in or out to cut unwanted feedback ot vibrations below 20 Hz, such as picked up by turntbles; There is a TREBBLE control, a blance control (samll knob) and a VOLUEM control with a built in power switch. Teh unit is desgined to be powered by the power amplifier, which means if wishign to purchase this unit alone, an external power supply (200V DC and 6.3V AC) will be needed, which I can custom build at additional cost.
Tubes (Varislope Stereo): 4x EF 86 / 2729 / 6267.
Condition / Work performed to rework these units: Both units have been completely overhauled, which means that in addition to repairs, ALL capacitors were replaced (with the exeption of a few special low voltage signal capcitors, that were intentionally left in place, where the vintage capacitors are actually better than new ones; (power supply AND signal coupling capacitors replaced!) All contacts, controll and switches have been estorred including the re-tensioning and lubrication of all tube sockets. About 13 hours of labor went into the restorration of these units (majority of time spent on capacitor replacement) Both units are technically reworked and tested - in great condition. Both units are sold and reliable performers. Physical cleaning and detail work. Physical condition: in great physical condition and clean,, but with some signs of it's 48 years of usage: some minor scratches, dings etc.
Lot: Available as: set of the 2 units, pre-amp only, power amp only.
Units Fully tubed. The pre-amp includes vintage Amperex tubes in great condition! The power amp includes the power cable, and if purchasing both units the special connector cable is included (vintage), which connects the pre-amp to the power amp.
