Re: Derailment Build
I started making a board for a Derailment many years ago and am thinking about resurrecting the project. Will the Hammond 269EX work for a power transformer?

Re: Sozo caps in Ceriatone Expression
I have premium sozo coupling and cathode bypass caps in my marshall-1987 inspired amp. I have also tried orange drops and mallory 150s in that amp. When I out in the sozos, the difference was huge - it was like all the gunk went away. As for the break-in time, I hooked a signal generator to the inpu...

Re: pots of choice
I have not used the clarostats, but the PECs are nice. I got mine from digikey at $10 a pot. Alpha and CTS are horrible. Some don't even conduct along the full range of the pot. I have a ton of alpha and CTS pots lying around - make me an offer

Re: Express relative volume to other amps
Don't know if it is too late to chime in, but... I have both a DIY 50W 1087-based plexi and a DIY express. I love them both. The TW has more gain and IMHO is a better lead amp. With humbuckers, you cat get a lot of gain. I have a strat with fralin blues specials that sounds great with the TW. My ple...

TW/Champ hybrib?
I did some playing a while back attempting to making a switchable Champ 5E1/SE TW (6V6). My goal was to add a second tube to function as V1B and V2 in a LP/EX preamp. Also, I was going to omit the tone stack. The original champ V1 would be split between V1A and V2B. I tried to leave the power tube s...

Re: TW-inspired "Marshall" 1987 layout/build complete
can you forward me a layout, I'm interested what cans you used for the amp. They look better than the traditional TW caps glues together! Here are some layout drawings that I found. You may have to move the cap under the PSU/bias board (look at the pix on my website). Also, notice that my newest ve...

can you forward me a layout, I'm interested what cans you used for the amp. They look better than the traditional TW caps glues together! The caps are F&Ts. Nice caps, but a PITA to install the way I did. You'll need a big punch or hole saw of do a lot of filing. I'll have to look around for the la...

Re: New Liverpool Tracks
I like it. Kind of like old Cactus.
I can't hear any bass though?

Re: Express rewire "correct" sockets still some hum
I did the out of phase wiring just to try it (as on Frannie). As for the grid stop on V1, that will reduce the gain a bit, but for a high gain amp like an express, I think that no resistor is what is needed. Grid stoppers also help to control parasitic oscillation, but mainly in the power tubes. So ...

Re: Express rewire "correct" sockets still some hum
On the hum subject. It might be the way you have your grounds on the main filter caps. In the original there are three separate ground wires for those caps, that all terminate at the ground lug where the two big caps stand up from. In your pics it appears you may have a ground lead running from you...

Re: Express rewire "correct" sockets still some hum
KGW - OK, do me a favor? If we've done this before tell me... Pull V1 and V2. Is the hum still there? Are your tubes biased to 40 mas? Do you have a good set of EL34s? Sometimes, especially if you have hum with V1 and V2 pulled, you could have a single bad pwr tube making the hum. OK, if all of thi...

Re: Express rewire "correct" sockets still some hum
Thanks rooster - I appreciate the suggestions. The hum is always there - power supply. volume, tone controls, etc, do not affect the hum. That is why I was skeptical about the tube sockets being the culprit. But I thought, what the hell. I tried pulling V1 and the hum doesn't go away. And yes, I'm p...
