Re: Humm , Mid bass , and Russian 6sn7s and filaments

Thankx Ralph ...can you tell me why the driver section had its own filament winding to begin with ? Whilst wiring the first chassis , I was very tempted to do just as youve spoken about above .re - feeding it from the 30amp toroid . Leakage - can you or anyone explain this a little more ( so I can learn whats going on inside these tubes ) .
Now - also regarding the newer wiring methods ( which ive only just become aware of ) does the Standby circuit still keep the HT B+ ( 300 vdc ) running ...as it used too ?? Because if I was to rewire the chassis's again , id prob have a switch for Filaments only ...and this also fed the secondary switch ( standard ) ..so that the Output Section ( 100 vdc bipolar supplies ) & the B+ ( +/- 300 vdc ) was together . At present I have it as original methods ...Heaters & B+ ....connecting to the second switch controlling the output 100vdc only .
Cheers for all the info so far - very informative .
Stu
