    Unknown potentiometer

    Hi, I am restoring an old Proton P1100 preamplifier. It has a lot of issues but I am slowly getting it back to working condition. There seems to be an issue with the potmeter controlling the base, so I removed it and tried to clean it. While it got better it's still not working as intended...

    Interesting Find... Proton 313 Powered Speakers

    Picked up a pair of Proton 313 Powered Speakers, they each have a 100W amp, they have 3 drivers all intact and in good shape, no cosmetic issues and other than the input sensitivity dial being scratchy when turned they sound good, I initially tested them with my iPhoneX with an 3.5mm to RCA...

    Proton 440 Tuning Issue

    My Proton 440 digital tuner is having issues pulling in the correct station For example 92.3 only plays in mono. Move it to 92.4 the station plays in Stereo (the stereo light comes on) This 0.1 tuning different happens with every station. What could be the cause?

    Proton D-1200 scorch-o-rama repair possible?

    Recently procured my holy grail amp knowing it was a basket case...impacted with dust, dirt, and who knows what else? (Who would DO such a thing to one of these?) I knew it wasn't fully operational, but could not pass it up in the unlikely event I could actually get it to cough to life. What I...

    Proton 300 Antenna Question(s)

    Does anyone know these antenna answers about the Proton 300: a) SWITCH? Does it have a switch for external antenna (can't find one but my Sangean WR11 does but honestly performs better with internal antenna) b) GYRO: There seems to be a gyroscopic antenna attached (I think - it looks like a...

    Proton D1200 strange behavior

    I have a Proton D1200 amp and every once in a while when I power it up and play something, the left channel is at a much lower volume and the sound is distorted ... if I turn the volume all the way down, the left VU meter will not bottom out, instead it'll read around 0.01 but no sound is heard...

    Tube Pre vs. Tube Power amp - my experience

    So as a relative newcomer to tubes, I was thrilled with the Jolida JD-302brc integrated I received in trade from another local enthusiast. Compared to every piece of SS gear I had ever owned, I could not believe the clarity of sound my system now delivered. Vocals had an immediacy I had never...

    Proton AP-1000 volume related issues

    Hello everyone. I have a very nice proton preamp but lately it has been showing a very annoying problem. Every now and then, out of nowhere, the volume opens up to a very, very high level and after a second or two it pops back to normal. I've checked the volume pot (it is a alps 10kbx2) and...
