Mission 300b parallel single ended

[duderduderini]

Hi Guys
Well I am taking suggestions for my 300b pse monobloccs.
I have the transformers, chokes etc etc.
Now I have a few ideas i have prototyped for design but thought I might throw it to the masses (well informed at that) for possible circuits
or ideas
The one i like the most soundwise is 6sn7 in srpp feeding a 6ca7 which then drives the 300b's
What have other diyers built in parrallel SE format?
Power supply will be clcrc with motor run ppropylene caps
Any suggestions will be truly appreciated
Thanks
Nick

Hi, i don't think 6CA7 is well to drive 300 PSE, because you may lost some details.

For the case i vote for schema of driver stage as same as AudioNote Kit one which using 01x 6SN7 for 2 chanels and 2 x 5687 for driver, just modify the inter-capacitor to 0.47uF for better bass.

In case you could find good interstage transformer, you should try this schema which strong enough to drive 211 as well.

Good luck
