I was already to cough up the $10 for this paper manual, when I clicked
on "BUY", it took me to an Ebay page that "does not exist". Probably
another useless ancient link to something that google dont seem to ever
remove. From what I've been seeing lately, google never removes outdated
links. I've been seeing around 35% of the links on google are obsolete
lately.

Actually I can understand why when you search for tube stuff you'll get more broken links. The extinct bound are probably going to get more of that in the future. Hell, I can't even find good food anymore.

Dude, I had to make the transition from tubes to transistors and so can you.. On tube TVs I had a superfast method which involved shorting things out. I took a grounded screwdriver to the plate cap ot the horizontal output tube which showed me immediately if there was B+ and if the damper tube was conducting. That ain't the half of it, I cured the Zenith ringing in the video problem.

You can do it too. I just had to learn just how fast transistors can be destroyed. With tubes I oculod short things out and see how long it takes for one of them to redplate and thus eliminate the need for a tube tester. That was radical, but it got results which paid the bills.

Solid state is a bit more tricky.

One of the first things is to figure out which section is faulty. Is it the amp ? If so that might be easy. The tone generators are a different story. In an older organ there will be 12 of them. Find an amp and connect SOMEHOW so you can determine all 12 of those generators work. If not, burn it.

I **** you not. It is too damn hard to find parts foro those things. Even if you do then they run out of tune whenb they heat up n ****. One thing you need for an organ or an older electric piano or anything like that is to have the tone generators working properly. If youu don't have that ytou willl be looking for germanium transistors, some of which have not been made in all my born days. Coils and capacitors it will take you three days to find on Digikey, if you can at all. And of course that depends on you getting the inforation on these parts, Digikey doesn't know, how could they ?

Another bottom line, power circuits blow first. It is entirely possible that your tone generators are fine. You have to test it with another amp. somewhere in there is the output going to the amp, if the thing powers up that is where you start. Connect it to anything. Even an elcheapo pair of PC speakers should do it. Test every key. If they all work we move on to the next step. You be lucky if all them tone gennies work and you just have to fix the amp.
