Knob dimensions + descriptions (please inquire - will add data as time permits ):

#6 = 37 mm x 17 mm - for 6mm round shaft - set screw - thick alluminum, inner core plastic $30.00

#8 is solid care alluminum with a set screw, surface texture is brushed and will fit 6mm shaft (about 7/32") - can be drilled out if needing it wider - solid core body, 7/8" diameter, 1/2" height - price $30
#9 = European knob: 11 mm x 9 mm for 4mm round shaft - drill out to needed size - as solid core alluminum - $25.00
#14 = SONY knob: is a brushed aluminum cup shape (2 mm thicjk aluminum) with a plastic center insert. 30 mm (diameter) x 28 mm (height) It is designed to fit a 5 mm knurled shaft, which needs to extend out about 2.5 mm from the mounting plate of your potentiometer / shaft mounting. The lower portion of the inside is wider and would fit about a 7mm shaft, which would need to extend out about 15 mm from the face plate. This means: if the shaft of the potentiometer of your amplifier extends out only about 15mm, that you will have to wrap it, so that it will fit the larger hole. There is no set screw. This knob is $25.00

#17 = 10 x 11 for 6 mm shaft - push on type for knurled shaft @ fine pitch - $6.00

For any vintage parts inquiry
-> please READ ALL

The reality about parts for vintage audio equipment that has not been made for decades in more than 95% of cases is:


Often I have to be very creative: pull used parts form similar equipment, custom modify, or even custom fabricate from scratch.

Thus: forget manufacturer replacment part numbers. Foremost I need ONE (only one please!) detail PHOTO form you, for each part that you need - plus the details form below (1-5)!

The correspondence for finding the right part for you takes a lot of time! To be exact: my work time that I need to bill for at my regular shop rate, as time spent answering parts inquiries is time not spent on my work bench. Thus: $30 minimum for the first part.
So: If you can find the needed part some place elese, please by all means do all you can, to do so! And: BEFORE contacting me!
I offer service for hard to find parts inquiries only, because: I myself know first hand how frustrating it is, not to be able to find them, and I need to bill for my time. Other than that: Glad to help!

CUSTOM ORDER ITEMS, that is anything that requires direct interaction - are $30 minimum for the first item. No parts inquiries answered over the telephone -> submit by e-mail only! AND: Custom Order Parts
not returnable and without any Warranty.

To Purchase / Inquire about Parts please provide:

1) One detail PHOTO for each part that you need:
-> SHOOT in macro mode, so that the camera will focus properly!
2) Please re-size the image in your camera to the smallest image size or use an image editing program for a file size smaller than 100 Kb, or I will not be able to review - No response!
3) Any additional descriptive information, such as: 3A): what the part is, what it's function is - where (e.g. in the cirsuit) AND how it is used; 3B): values (example: capacitors, potentiometers, transformers, semi conductors, etc: K Ohms, uF , voltages, current requirements, etc. AND: physical dimensions (in inches or millimeters) - especially important for belts! 3D): type: for example "square" or "round"
4) Equipment type (e.g. "table top radio"), Brand name, model number, year manufactured, etc. for your equipment
5) Please care to include your ship-to ZIP code for accurate shipping costs.

Example: Photo +“I need a 250 K linear stereo balance potentiometer with an 8 mm knurled shaft, 24 mm mounting depth, with solder lugs and center loudness tabs for a Marantz 2226b Hi-Fi stereo receiver made in 1976 - Shipping to Chico, CA 95926, USA”

No parts inquiries answered over the telephone.

In response to your photo AND complete inquiry information
->submit items 1 through 5 above, or I iwll have to bill $25, before I can respond! )
I will e-mail you one photo of parts that potentially may work, to offer purchase options, or for discussion if nothing closely matching is available - BUT: After sending you the first photo / e-mail, I require a non refundable $25 deposit to compensate for my work time, before further materials can be e-mailed to you.

NOTE: Due to the nature of obsolete vintage audio equipment and it’s obsolete parts: There are NO WARRANTIES expressed or implied, that I may be able to help, nor that I have or can provide the needed part, nor that parts that I may have will work, nor work for for your specific purpose - even if it may look it will work! Your payment pays for my work time only, to review your materials, search my stock, equipment, or parts sources, and most important: for the time needed for correspondence - thus: NOT RETURNABLE.

Although: All of my efforts will focus to aid to the best extent possible for a solution to provide parts to get your equipment working again! - Proud of 30 years of experience in working on vintage Audio Equipment!
AND: with those who are valuing my time with payment I may gladly share any information such as: where to potentially find it, or how to substitute / reapir, etc.

Alternatives to my $30 minimum and "not retunable" policies:
Browse my web site and simply purchase available items via the Paypal shopping cart on my web site. Or: If I get enough inquiries for items that I may be able to offer readliy available, I may in response to your inquiry make these items available to the shopping cart, saving you the processing fee (and my work time!).
