Treble pot on RF #102

[ijedouglas]

A 250K pot measuring 400K is very strange as I doubt the pot would have been used enough to get the wear to increase the value that much. The other option is that the pot was opened and material was removed from the wafer.

I assume that you have experimented with this, did the pot value really make much difference?

I would agree but I think that may be a typo on the bass pot. The bass pot should be a 500K that probably measured low at 400K. In the pic I have (after skyline conversion) it had a CTS pot for the bass.

For history's sake:

Yup, same pic I have. Mid/Bass CTS and Treble Alpha/Mouser

Yess you are right! A better shot than the one I had

Mid pot CTS type usually have a 10-12% taper like Alphas

Is the bass pot a CTS 2-35?

Since the bass pot isnt changed as per layout and has the same markings as on pic; member Max explained in this topic: https://ampgarage.com/forum/viewtopic.p ... 66#p138066 "The 500K bass pot is IMO a Gibson guitar pot. The date code indicates 137 = CTS and and week 02 in year 67. This makes sense because AFAIK Gibson had changed from Central Lab to CTS already in '67. These 60ies 500K CTS guitar pots are AUD and AFAIR their taper usually measures around 30%."
