Haven't heard anything about an equivalent.
QService lists new at $140.
If that won't do it for you, try finding one from somebody who strips them used out of
salvaged instruments.
If this is an 'again' thing, like you said, you better get into that horizontal output circut, and find-out what's causing your problem.
Frankly, if I was you. I'd just buy a parts unit from one of the salvage companies, or off Ebay, and salvage any parts you need out of it for the repair.
