I've come into some 6883B tubes (12V 6146B), so I decided to make a pair of monoblocks using them as a output tube. From the spec sheet, looks like one can get close to 100 watts from a pair of them.
To ensure reliability, will go with a separate screen supply at slightly under 250V. Plan to make plate voltage around 600 volts. Will get transformers from Heyboer for power and output. Reckon a 100 watt at 6.6K CT should do the trick. Going to use 6BL7 tubes for the input/phase splitter.
Anyone else try making an amp with these? Looking for some feedback/input on this. The 6883B seems like a good candidate for output tube usage. It can provide as much power as a 6550, and since they are NOS, no worries about questionable quality and high prices of current 6550's.
