6b4g SET. B+ supply 5r4 with critical inductance LC filter followed by one additional LC filter for each output tube. Critical inductance LCRC filament supply. UltraPath cap, no cathode bypass cap. ElectraPrint output transformers.

Drivers on their own chassis.
Power supply for drivers on it's own chassis. (not shown)
Tube rectifier with critical inductance LCLC filter feeding a depletion mode MosFet based CCS feeding VR tubes shunt regulated B+. Heater supply SS bridge rectifier with critical inductance LCLCRC filter.

This three chassis stereo amplifier drives my mid range speakers (Fostex FE206E) and my tweeters (Large Heil AMT).

I use a SS amp to drive my JBL 2231 15" woofers in JBL 4503A-1 enclosures.

Is this like a 6V version of a 2A3? Nice looking amp.

I have a very nice Silvercore 2A3 amps that uses a 6C45P transformer coupled to the output stage. 5U4G rectified (works with 5AR4 and 5R4GY etc.). This drives my Horning Eufrodite Ellipse speakers beautifully.
- Yes, a 6b4g is a 2a3 with a 6.3 volt filament and a octal base. nt - Tre' 09:16:41 07/19/24 (0)
