The new to me PL700 arrived safely today. Yes I know its the first generation and a little more effort to rebuild however those early 70's VU meters get me every time.
Peeking at the back I note that almost all the transistors are original xpl909's with hand written hfe values along with one rca 2n3773. The pnp drivers are half motorola 7439 and half 7311's. Need to pull them all and test before even thinking of applying power to establish a baseline to work from. Also need to find one transistor cover or figure out a way to protect myself from an inadvertent high voltage mishap.
This amp must have been n a band PA system, there are 1/4" output jacks mounted to the right side along with the standard rear panel stuff. They are there, poor camera operator at the controls
Not too much rust, dents or dings, here is the serial number and transformer.
Will be a week or two before I get started, need to clear the bench of a couple of client repairs first
At the minimum without even applying power believe I will need the WOPL control board, main caps, outputs, snubber and speaker relay. Many thanks to Joe at WOPL for the reply to my email and the suggested upgrade path. This forum rocks.
Since I am the 700 newbie in the room feel free to fire away with comments, suggestions and any other cool off topic thoughts to help the thread along
