Proton 1100 preamp manual

Service Manuals. Watch Report This Ad. Item It is something rare, an overachiever, a unique combination of reference-level performance and compact, convenient design. It is at once familiar in size and shape and yet completely new in aesthetic design detail. It is the perfect mix of traditional function and cutting-edge This is a run-through of the functionality and cosmetics of my Proton D amplifier. Proton D Amplifier Run. Now tested on several other power amps and it still stands out, last one i tried was a Kenwood basic m1 wich was connected to a set of bose acoustimass am5 by the sigmacables!!

These speakers never sounded good in my ears but it was like the proton ap activated or lifted the damping factor of the kenwood amp, for the first time i experienced chewinggum bass from the speakers!! Looking for original manual. I just scanned my copy of the original manual and uploaded it to this site. If you like, you can private message me an email address where I can email it to you.

BTW I have sent this manual out to nearly 60 people so far, so there are still a few in action out there! Another happy P owner. Repaired a few too many of these many years ago Is my memory right that transistors are very hot in these and because of this many electrolytic caps are shot?

Voltage ratings of electrolytic caps are chosen too narrow. Also loose PCB tracks. Extremely high possible output voltage too. Sounds very very good as often with high octane stuff. Last edited: am.

I wanted to give my preamp a bill of health, and put it in to regular use, but had put that activity on ice for the last decade without a good schematic to ease the process of inspection and performance testing. There were a few Proton preamp types so please consider that I only rely on my memory. If I am mixing up the and the then I am sorry for stirring up stuff. So please check if the info is applicable! Yes it is a preamp but if my memory serves me right the stated things are true.

Bad part choice and not enough consideration regarding heat development. Often the transistors were shot too. Thin ice but info from other devices: if possible choose highest taps of the primary side of the power transformer. Never had a schematic of these but managed to get them back to life again but always with that bad feeling it had nearly unrepairable PCB damage.
