C3m driver 300b

The rare Siemens C3m sounds even better, all resistors apart form the Cathode Resistor remain 5 = C3m Poweramp is still the B SE Job (Fugue/Legacy B) with the EL84 Pethode Driver and Valve regged PSU's, very similar to the older JC Verdier unit. At the moment I'm running 2A3 Outputs as these sound better with the Speakers (Hoerning. The output stage uses 3 parallell B’s running at vdc, negative bias or for the fans of cathode bias vdc.(this is all possible with the new power transformers) The input tube a 2C51 western electric direct coupled Loftin White circuit to the driver tube aC3M from Siemens and as an interstage (if used) LL/18mA, penthode www.doorway.ru: fdg.  · C3g is a nice driver for DHTs but it is starting to run out of steam when driving a B hard so if you are maxing out the B then better to use the C3m (a point Thorsten always makes). Agree with the current split 70mA for B, 20mA for C3m anode and 10mA for the screen grid chain.

ECC99, ECC88, E88CC, , 6N6P, and d3A (triode strapped) are all great B drivers. 12BH7A is another common one. You need a low drive impedance for the B, though, as its input capacitance is on the order of pF. I use a cathode follower. If you don't mind a little sand in the glass, a source follower works well here as well. ~Tom.

Some people have told me that b amps sound better when the driver it was a one-off c3M pentode driven B with Electra-Print iron.
