Er... I was looking at the Kelley90 schematics you sent me to? It is in the physical pics - Francesca and Kelley90 - and written in the schematic fro Kelley90. Are you with me, Brother gearhead? Er.. I trust people here, no problem. Actually, I thought that some of those schematics from Blue Gtr wer...

gearhead - OK, I see what you are talking about and yes, I have read where many here are using this pwr supply cappage layout. But it is the Blue Guitar schematics that I am looking at mainly. They are just presented in a more organized way and - without that weird 470K resistor to ground that bridg...

OK, I get the dual 40uf + single 40. This has to be correct because they are all the same size. Do you think this was original KF - or were the originals replaced? Thank you for this answer, gearhead. What confuses me here is the schematic that shows two 160uf caps in series with the bridging 220K r...

I cannot open that BOM, it seems to be some type of Excel spread sheet and I do not have that on this computer. Care to send me a PDF file of it? And if not, then I can tell you where I purchased my Allesandro branded PEC pots that are probably what you are finding in that list. Remember too, that y...

Omar, Hi. Could you find and post the physical specs on the new
laydown version of the Tonesluts PT? I will have one in a few days from Chris so I can send you that info, but maybe you have a better way? Thanks.

This is some kind of Excel spread sheet? Is this in PDF form? Thanks.

Looking at the pwr supply and the 160uf caps, where did KF place the 220K resistors that run in parallel? I am looking at pics of Francesca, for example. Are they just strapped onto the caps and hidden in the silicone or is there something more clever that I cannot see? BTW, can I assume that these ...

Lonely Raven - Arghh! I am working with you so much as a wood working magician I forget that you are in this as deep as the rest of us!!! So, regarding TW pots, yes, I think your suggestion is a good one, with the 'group buy' but I don't think it necessary here. Honestly, even buying the PECs at who...

OK, to gearhead goes this answer: At 12 o'clock with a perfect 30% taper, the pot value being 1meg audio, the pot's resistance would be 300K. With 10% taper it would be 100K. Fender's pots at 12 o'clock were typically 500K, or half the value of the pot - and yes - BTW, they were called 30% taper. I ...

Thanks for all the help here. I have to agree that not only is Precision a quality potentiometer maker, they are also very responsive to my questions and needs. One thing I don't understand however, based on the responses here, is why none of you seem too interested in 30% taper audio pots. Why is t...

Hi. Here's a question for anyone who can direct me to the right part: Where do I find 1 meg volume pots with 30% audio taper - with the quality of Clarostat? Anyone? I think I have tried any and everything, now including the Allesandro part which is a 10% taper. Is 10% the max for Clarostat? Did the...

Its an added shield that surrounds the entire coil, not hi-mu but sort of. The tranny will still work fine, but you may have reduced the overall sheilding of stray 'electons' or magnetic 'pulses'. Just find something similar in size - copper foil is best - and carefully patch the new piece on with a...

OK, I assume you are refering to the AC input voltage leads on the primary side, the AC filament pair on the secondary side, and the secondary AC (ultimately B+) leads? And you probably have the knowledge to have already grounded the center taps on the filament and the secondary AC coils? If 'yes', ...
