Hmmmm, what model of Mits and which tube ? We've had a couple with
really bad coolant leaks and the tubes are just fine.

Thing is, on the Pioneer, 101V might be right, you need other
observations to determine that. Can you determine if it has seperate
HOT and HVOT ? Look at the yoke plugs. Where the red wires went they
are all hooked together. Do they go to the flyback or not ? Sometimes
they go to a somewhat smaller transformer.

Now lemme tellya something about electronic design. They do not use a
darlington because they want to feed it with a high current source.

When you start finding your way around that board, in the PS there is
a darlington, and it breaks the rules. It is fed with a low impedance
source. But that is the exception. Normally darlingtons are used
because of lower drive current requirements. That means usually, if
your DVM reads 0.468 E to B forward, something is wrong. Pioneer has a
habit of using these 2SD12 somethings, and in some cases you can just
throw a 2SD401 in there, and in others you can't. And it is very
difficult to tell without a print.

Also, inspect that board very carefully for bad solder joints. More
than one have been fixed by simply resoldering them. Of course it is
still $300 because it is such a bitch to do, but actually those sets
are relatively reliable.
