Preamp is a mixture of a JCM800 and a 5E3.
First valve is 2 cascaded stage with a "low" input in between, like a JCM800, 2nd valve is exactly as a 5E3.
Power amp is a pair of 6K6GT, cathode biased, 268V, for about 8W or push-pull pentode power!
Still some bugs to iron out, fairly noisy, but it's a prototype built on perf-board! Not bad eh?
Recording was the amp slaved to a dummy load, then DI'ed into a Mackie ONYX400F, Voxengo Boogex is used for cab sim.
