Re: Cleaning Switch contacts and machanisms on HP239a Oscillator

At the risk of extending this thread too long.....
I used to repair 239's for HP back in the 70's.
Camolin was my go to product for cleaning the switches. Worked great, never had complaints from customers.
They were a great oscillator in their day.
By the way I was fortunate enough to meet Dave Packard personally and had a brief conversation with him....Really nice guy.
Good luck with your restoration.
