Hi,
Need advice with regard to using the gz37 in the kit1 instead of 5u4g. Even when I rewire the main trans to 240v (my main is 220v) I still have 450V on B+.
I feel this is a bit too high (dont want to shorten the life of the 300Bs). Im thinking 3 options:
1) place a 100ohm Mill wirewound resistor after gz37 should reduce the B+ by approximately 20v, but I've read that more series resistance will negatively effect the sound.
2) reduce the input cap to maybe 10uf or lower, but Im afraid that this will cause quite a bit of hum with my 98db speakers.
3) order a new transformer from Brian, I read him somewhere in this forum that he has a new patch of transformers with more correct voltages...
what would you do?
Thanks and regards,
Vi
