Re: Blackface Vibroverb Output Transformer Recommendations
at the price of trannies & parts , I would blackface a super reverb and put in a 15" baffle something like this beat up one that went for $450 needing speakers & baffle http://i.ebayimg.com/images/g/HAYAAOSw3gJZLHYi/s-l1600.jpg http://www.ebay.com/itm/fender-super-reverb-/112423896433?_trksid=p20476...

George Westinghouse probably could have afforded to keep Tesla from dyeing in poverty, after all the money he made off him.

Re: 6G6 b+ voltage & 5881 tubes
Took me long enough to get used to calling the mains B+, don't know how long it will take to think of nodes as , a b c d, instead 1st 2nd 3rd 4th https://youtu.be/JhaY9oDNvdk And now you are confusing me :-) When I hear "mains", I think of the AC voltage at the wall socket, not a high voltage DC so...

Re: 6G6 b+ voltage & 5881 tubes
Your confusing me with your terms,( B+ =HT ?), the 6,000 to 12,000v supply line that runs through my backyard before the step-down transformer isn't considered high tension around here,just post substation supply line, this is what WE call High Tension 138kv to 780kv https://upload.wikimedia.org/wik...

Re: 6G6 b+ voltage & 5881 tubes
Electrolytic for sure, I think of them as bias caps , or cathode bypass caps when cathode biased, like the preamp tubes , all caps could be considered filters that's what they do, even in the tone stack, I think of the power filter caps as the filter caps

Re: 6G6 b+ voltage & 5881 tubes
well it doesn't hum , quiet as a church mouse, I hardly think the filter caps caused my plate dissipation to go through the roof, if they were failing to ground my B+ would drop and my dissipation would be less, not to mention a fuse blowing , the bias circuit opening up would more than likely be th...

Re: Deal or no deal
That Bandmaster sure would be the cat's whiskers, with a Bassman OT,sitting on top of my Blackface 2x12 cab fitted with a 4 ohm d130f or evm 15l, OH BOY!
that's a whole lot of whoup a** for around 7 bills
