Re: 1S1 upgrade kit available
Sorry, it's not an upgrade.toggle quoted messageShow quoted text
Mod Kit 050-1350-00 was created in 1980 as a replacement for Q324, after the original Germanium transistor, 153-0532-00, and its raw-stock parent, 151-0130-00 (2N1195), became unavailable.
All the kit does is
(a) replace Q324 with 151-0221-00 (2N4258), and
(b) add a diode drop in series with D304, the tunnel diode controlling Q324, to accommodate the larger Vbe of the new transistor.
The mod kit is useless until your existing Q324 fails.

So what does this kit comprise?
