Like the title says, I am going to be ordering a mess of caps and/or transistors for a Pioneer CT-F2121 Cassette Deck that I'm trying to get back into fighting shape. I am in the process of making a list of parts to order and replace. Here is a list of the transistors used in this unit:
2SA564-S
2SA564A-R
2SA721-S
2SC1327-T
2SC1419-C
2SC735-Y
2SC828-R
2SC828-S
2SC828A-R
2SD234-O
2SK30-D
In your experience, are any of these transistor types prone to failure or becoming noisy? I don't see the usual offenders that I often find in other Pioneer pieces from the era.
