Separate names with a comma.
So there is some change but still a lot of separation from that one power tube.
However you did not raise them much.
You can place 26.1 with 24.7...
Do not confuse what @Matthews Guitars said and what else should be done. Yes you are doing as he mentioned because that is what should be done...
In post #61 you mentioned one power tube, not all four as asked. It is imperative that you/we know all four.
Please carry on.
And that right there..................
is why I first mentioned the tremolo circuit. ;)
Ooooph, I forgot he changed those 100k mixers back to 470k. :)
But check them first, please. I have been trying to get you to rebias and post measurement values for like 3 or 4 days now. Shezz. :D
I want to...
It is a 1959S model, late eighties so 6CA7/EL34.
First get a good electronics contact cleaner/lubricator and apply it to the socket prongs and tube pins.
You can do the same with the preamp...
You and others reading have a need to understand as I said things can change when you move tubes around and re-adjust bias points not to mention...
Damn Lemming Syndrome.
But alas, 'tis is Nature and its divine wisdom.
Well yes, kind of like that.
Just give us the power tube measurements right now.
Heaters pins #2 and #7 are VAC.
Pins #3, #4 and #5 are VDC.
Everything handled inside of an organization by the pontiff and his henchmen. :hmm:
That is just like so many other high and mighty organizations.
Check/measure all four power tubes to see how they may have changed or are balanced.
Never sell out!
Run, live to fly
Fly to live
Do or die
Won't you run?
Live to fly
Fly to live
Now did you rebias the damn amplifier? :D
Please give all measurement details.
Those are all fine. But it sure does not hurt to check things.
By the way whenever you open an amplifier I consider it good practice to make...
That makes it even worse. It paints a shady picture. Of course I always knew the NFL to be shady just like all other sports-money making efforts.
That is normal at the TREBLE wiper out to the PI especially for an old amplifier.
Not if it is the preamp ansd PI power supply filters are allowing or causing (part) of the issue.
Killing the signal prior to the PI can stop it...
Its can be ironic and is funny at the same time because the real problem could be the power supply filter capacitors.
@myersbw and I have...
