Help with vintage pre-driver TO039 transistor replacements

[tnsilver]

Hi everyone. I have a Panasonic quad receiver with one channel blown. I've placed an order for the outputs replacements (originally 2SD217), substituted by MJ21194G, but there's a couple pre-drivers (TO039, gold plated leads) I can't find replacements for.

These are:

1. 2SC696A (NPN, 0.75watts, 100Vcb, 60Vce, 35 MHz)
2. 2SA546A (PNP, 0.75watts, 90Vcb, 80Vce, 50MHz)

The alltransistors website replacement search yields nothing for me, but a list of obsolete devices.

Appreciate any help.
TIA, Tom

If can't find equivalent in TO039, TTA004B and TTC004B perhaps are viable replacement, though you'd have to improvise some kind of heatsinking measure.

Possibly 2n3440, 2n5415

Transfer over heatsinks

Thanks guys. The 2N3440 and 2N5415 seems like a good match and are available on mouser. I was also referred to the same subs by an exert in another forum. Thanks so much - you guys had saved my day!
