The Amp Garage

I would do this. Maybe change to an AC coupled cathodyne if not liking the DC coupled cathodyne. Only need 2 resistors and a cap. Steve, Do you know which Magnatone (or other) model that amp is that you posted the example of? The tone circuit looks interesting (as compared to a Tweed/18W type). Tha...

Great sounding amp!

I love that heater/amp!

I have been a huge Holdsworth fan for many years. He was a genius and a wonderful person. I was fortunate to see him six times and even got to meet and speak with him on a few occasions. His tone on Secrets using an early Boogie Dual Rectifier (s/n <500) into his Harness and reamped was probably amo...

That's one of two options. The other is hanging it from the OD2 plate.

I like that idea too, Martin.

I built a 6V6 Plexi many years ago. It ran at 440V on the plates (JJs) and used a 7k6 20W Marshall OT. Fantastic sounding amp. I would probably go with the 8k taps.

I really like the treble bleed. It helps balance the clean and OD tones. I usually build the amp without then use a pot and a .001uf cap to dial in to taste. I've always ended up between 100k and 150k. When building a board from scratch I add eyelets for the extra resistor and cap. On this build I ...

Well I’m finally beginning this build. Any opinions on Orange Drops versus something like Sozos or Jupiter capacitors? I’m still going to initially build it with the orange drops that come with the Mojotone small parts kit I have here but I already feel like upgrading to something more “authentic”....

The primary impedance for an Express OT is 6k6, not 7k5.

Looks great! That'll be a fun amp to play.

There was a big backlog of folks wanting to become members, and I've let many of them in just now, so I'll be watching out for shenanigans and spam.

Carry on, and happy holidays!

Excellent!

FWIW, I ended up using the extra node for the screens but used a 10k dropper instead of 22k. That put the screen node at about 290vdc with 350vdc plates at idle. About 10.2vdc on the 120ohm cathode resistor. I’m now building a 15W Liverpool in a sister chassis using a custom Fender Deluxe OT that i...

I recently built a 15W 2xEL84 Lightning clone using the alleged Matchless transformers built by Heyboer and sold on amppartsdirect. The 15W 2xEL84 OT has a primary impedance of 3800 ohms. Less than half of what most 2xEL84 amps are and about the same as their 30W amps (that OT is 3700 ohms). The am...

F70 for the win. Nice playing!
