De impedance of the circuit varies with the frequency admitted to the tone stack. I doubt there is much to replace.

I take the easy approach....I get the planks I want (from a different supplier) and have it cut to size how I want it. Piss 'm off to cut straight...

About the PT... Msart idea. Never thought of that one. You could also make a small powersupply by using a cheap transformer, diode couple of caps and a couple...

Based some specs on the web, the max rating is 0.3uA. I would guess that for 25 x EL34's you should have enough on 10mA. I think it is more important to take...

One other reason could be that the OT is picking up "hum" from the magnetic radiation of the PT through the chassis. You can verify this by disconnecting...

I built a DlxRev kit once from TAD. Pretty straight forward building. I wasn't too fond of the chassis though. I have seen better ones in the market. The...

There is no reason why a cab should not look like a nice piece of furniture. The box needs either a closed or open back (both are out of sight). For the rest...

That is why they use the divisor switch 1:10 which divides the input voltage by 10. Now allowing you to measure up to 2.5kV if your probe itself can handle...

There is a guy in Holland "Richard Nijboer" who has designed a combination of Opamps and a tube for a Tube overdrive including a schematic and a...

You might try a "paint"store if they have something to remove the "lacquer". This transformer has definitely been vacuum cooked in lacquer...

Bruce I agree with you on this one. The only positive thing about the high speed diodes I can think of is that they tend to produce less noise. But You would...

I have a combination of both pre-amps in my diy champ. I am assuming you mean that the 5C1 is not as loud as the 5F1 (which is definitely the case). However...
