Part 9: up to 9 watts

One of Ampmakers mod suggestions is to change the mains transformer output tapping so that a differnet output voltage is produced. By going for the 0 - 190 output, the DC HT voltage becomes 250 volts and the output power is 9 watts rather than the full 18 watts.

NB: this is still SERIOUSLY loud. Through my home-built "Marshall" 4x12 , this was pretty impressive. And it wasnt even totally cranked. Plus it was going through my "BitMo clone" attenuator.

What this lot sounds like when totally unleashed remains to be seen... Reminds me of that old Motorhead thing "Deaf not Blind!"

Anyway, heres the mod: (crap pic I know, rubbish camera...)

Showing the power transformer and the leads to the rectifier diodes - using the 0 - 190 taps rather than 0 - 275. This gives 9 watts output maximum
