Suggestion for upgrade of a Fender Blues Junior amp Hi !   I am upgrading my friends Blues Junior.   He wants more clean and a little   bit more power .   Please let me know if I am doing   something wrong.   I am planning to :     1. Replace input grid resistor from   10k to 68k     2. Replace Blues Junior OT with   Deluxe Reverb OT.     3. Replace otput tubes to 6L6GC.     4. Replace grid stoppers from 100 to   470 / 2W resistors.     5. Add Choke to power supply.     6. Add variable bias for output tubes.     7. Replace PT with new one with   following spesifications :     230VAC / 300VAC - 250mA + 45VAC - 100mA +   20 VAC - 100mA + 6.3VAC - 4A .     Speaker is Eminence 50W / 8 ohm and should   handle increased power . Power supply caps   are rated at 500V ( surprise ! ).   I hope I will get more bass and wider   range of clean sound.     Is there anything I should take care of ?   I am not shure about PT specs . Is 300VAC   enough for 20 to 25 W and will Deluxe Reverb   OT handle this ?
