QUAD 33 Pre Amplifier Spare parts 3 x 28mm Filter Pots Bass Treble Slope These are 28mm All Short Throw All 3 28mm Potentiometers included, all original, unmolested fully working, treated with Servisol, no noise.NOTE. The filter pot can only be used for this application, it will not work as a volume pot! IMPORTANT NOTEThis might get a little confusing but QUAD used different potentiometers over the years and you will need to match them up if you want your wheel rotation to register properly on the front plate.There is 2 can diameters 24mm and 28mm (both approx sizes)Both type cans can have long or shorter rotationSee the listing photo to match your filter wheels and choose the type you need.Message me after purchase to confirm. It’s easier to find your type by looking at the “slope” wheel, it’s graduations have a greater variation, the bass and treble wheels are not so easy to differentiate, if in doubt message me. For this reason I only sell them as a group of 3. Filter wheels not included in sale. From my personal collection of used tested and working parts, I have too many and not enough time to use them before my eyes give up close work! All parts have been taken from complete working units. Hoping these bits and bobs will help you get your 33 up and running again.Be aware though that there will be security markings on some parts due to a few unpleasant experiences in the past. There may be some slight damage to the wiring from the desoldering operation but nothing that cannot be easily repaired as you fit them. Photos form part of the description and if you require any more or information of any kind it is only a message away! Always happy to discuss vintage QUAD problems, I have experienced most of the common faults multiple times! Happy to combine postage on multiple sales. Will use the appropriate service dependant on total price and weight.All parcels will be insured to the value within. Thank you for looking.
