#1. I have been searching the WWW for a Manual for a recently acquired Exact Electronics Inc. Model 528 Sweep / Function generator. Big ZIPPO. I'm not looking to bum one. I am willing to pay good money for the Manual, but it appears Exact no longer exists.
I have searched EVERY Manual site I could find, and I have come close, but NO Model 528....
#2. I have a Tek Model 7623A 'scope that's driving me nuts! One day, I turned it on and heard a very low 'click', like a fuse blowing. I have NO trace or even a 'power' light.
I have been working on this thing for ...TOO...long.
I have a fan, but it's pretty weak. I have found:
A blown fuse.
A blown resistor on the P/S.
One of the power-on micro-switches was broken 'Normally Closed' instead of "Normally Open".
I have a Manual by Tek called 'Troubleshootig your Oscilloscope". This was pretty useless, it just pointed me to the P/S. I also have the Op / Service Manual. The voltages look OK. Yes, I removed the plug-ins and same thing.
I have asked for help on the "Test Equipment Digest" on QRZ, and NO replies.
I have had this scope for over 20 years and I REALLY hate to scrap it......
