SAE Two PA-10 preamplifier

Hi John,

You are very welcome, and I'm glad to be able to help. This preamp seems to be a bit rare, and I still haven't found any service information for it.
Even though I am a die-hard tube guy, this is one of the few SS preamps that I really like.

The resistor in question, R162, is 270Ω. Coincidentally, the resistor right beside it, R161, is also 270Ω.
I'm thinking perhaps power supply decoupling, as there are two film caps right alongside them.
