Classic gear from yesteryear; vintage audio standing the test of time.

It's not a preamp. It's an adventure!!!

Jeez Pete, you seem to be on a mission to champion every dubious design of excellent manufacture out there. I am pretty sure there's a germanium and selenium preamp in your future.

But until that day comes, you should include among the naysayers of the Crown 150 the actual Crown company, themselves. Consequently, you can download for free any information you might need to improve your preamp. The link is included.

You might also look into the Audio Amateur back issues for the rebuild information on your preamp. From what I could see, the phono circuit looks like a goner. But any section which is op amp based can be made to sound great by figuring out how to incorporate modern op amps made by Analog Devices or Linear Technology. Also, whenever you see a 2-5uf electrolytic cap used as a coupling cap in the original schematic, plan on replacing with a 2-5uf/100V film cap. That alone should at least update you toward the end of the 20th century.

Good luck, Bob
