I have an older QSC model 1400 in with some blown output
transistors (uses 8 per channel). Original outputs are Toshiba
2SD424 and B554. QSC doesn't sell parts for this amp any longer
because of it's age. Is there a reliable source of these outputs,
or should I replace them all with something newer?

These are a common output transistor and are readily available. MCM
electronics has them as does MAT Electronics and others. Look
around. Dalbani out of Florida should have them as well. IRRC
Dalbani is hte least expensive. That being said, these are usually
$4-$6 each.


**I tried doing business with Dalbani about 5 - 6 years ago. I did a
search for a NLA LED display for a Krell CD player. They had the part
advertised for about $20.00. When I ordered the part, they suddenly
raised the price to more than $200.00. I have not dealt with them since.
Is this their normal method of doing business? Have they improved?

FWIW: The customer baulked at the revised repair cost and decided not to
go ahead. The client lost, I lost and Dalbani lost.
