HP 8620A SWEEP OSCILLATOR

ALL SOLD

Dismantled for Spares

The HP 8620A Sweep Oscillator has been carefully dismantled down to 'Assembly' level so that I can cannibalise parts for use elsewhere, or maybe some of it will be useful to someone else to repair their unit. Please Contact Me if you need any of these parts.

This was the state of the HP 8620A before dismantling.
Some front panel parts are missing.

NOTE: I can not guarantee that all the parts are tested ok, but on powering-up the 8620A with a Variac all seemed ok. The power supply provided all the correct voltage rails and the Sweep Out was the correct ramp or voltage level in Sweep, ΔF, CW, CW Vernier and Stop modes.
