Re: Jcm900 problems... Help needed!

Measuring voltage will only tell you if you are getting the correct B+ and B- to operate the IC, you need to scope the input and output to see if the chip is failing with regards to the signal flow. You can buy the M5201 from Antique Electronic Supply for $5.95, p/n is P-QM5201
