OK again. Im doing the bias mod on my 5150. Found 2 pdf documents on it... Pretty sure one was the old one that was on Jerrys site. Its all easy.. But I want to install the test terminals as well, Which I will find at radio shack, And IM making
the pot accessable from the outside. I mean this is basic engineering and IM not going to screw anything up. Its mostly finished... Except I dont have a bias probe or access to one.
I have a nice multimeter though. The layout is going to look about like the XXX with the terminals.
I was able to get a ballpark reading somehow using volts, i think i had it set to like 42.5 or something on
the XXX. These powers are sovtek wxt 6l6 tubes with about 40% life left.
How do I use the meter to adjust it in volts or whatever... All the little thingies the meter has on it.
What number should I make it. Im using a 6.8 resistor and a 10k pot.
So when I stick the probes in the terminals... What numbers am I looking for here?
Thank you very much
