Re: Princeton reverb 12at7 voltage is inconvenient.
For the price of a reverb driver transformer and the tube you drive it you can get a SS reverb section the only needs 5 volts .

Re: Just got this Bogen Challenger CH8 working, now what?
This comment might be short sighted, but how does one become a better guitar player when you leave your axe at a Cigar Lounge all week long?
I missed this the first time through this string.

Re: Help with circuit
Well you first need to learn about what negative feedback is and what it does to the tone and response of a amp. To save someone from from having to type up a 25 minute reply to you take stroll over to the Aiken amp site, go into his white paper listing and there you will find 2 articles on negative...

Re: Keep a lookout.
The heat sink is bolted to the SS recto bridge.
This whole PS board however is on output tube side of the chassis, but I think the issue might be more age related.

Re: Output transformers
I am working on a real DS right now trying to take some gain out of it, but more importantly hiss. Anyway with 100% strong testing 84s in this amp and 120 vac coming in the amp in stock form is hard pressed to output 12 watts rms. That Hammond will live forever in that circuit if the core is close t...

Re: PT reverse engineering problem
The solid core black wire must be the shield attached to the core.

Re: Deluxe Reverb power transformer change?
The main difference between the two amps is the responce time of the two different rectifiers used once the output stage starts to really load the power supply hard. The 5U4 has a much higher internal impedance then the GZ and there for will respond a bit slower under high current draw conditions. N...

Re: Build Ideas for OT with 4.3K Primaries - Cathode biased 6L6s?
Sounds like a Wards Airline 8517 cut back to only 2 outputs might be a interesting way to go.

Re: You never know!
I can see how this could happen with the Marshall that’s hand wired because the cathode resistor I would assume was soldered across the cap and then both soldered in as a assy, but when your installing a cap on a board that’s marked for correct installation then that’s a real screw up!
