Welcome! Since you found two amps I'm guessing your dad used the bigger amp (1.5t) for the 'main' system and the 200t for a second room? But if you're only working with one room, the M-1.5t should do the job nicely. But either should be fine if it meets your power output needs. For the volume control, in some cases it's hard to get the liquid into the pot for cleaning. If the CRC doesn't change at least reduce the crackling, I'm guessing it isn't getting into the wiper of the pot. If you are comfortable with removing the cover so you can get direct access to the pot, a straw on the CRC sprayer should be able to get the cleaner in there. Look for a little opening/notch in the pot body to allow access. Spray it with power off (and the system unplugged and sitting for 5+ minutes), rotate the pot fully back-and-forth 4-5 times, then reconnect everything and try again. And @Balok had a good insight as the Balance pot can also get distortion into either audio channel. In fact, if you've gained access to one pot, it's a good idea to clean them all. Good luck.

If you have cleaned the volume pot and it still crackles or you have channel drop out you probably need to clean the balance pot. I am no expert, but I use fader lube on pots and contact cleaner on switches. Both caig deoxit.

Greetings. Thanks for the add. My dad owned a burglar and fire alarm company from the 70s - early 90s. In addition to installing alarms in high end homes, he installed Hi Fi on the side. We always had a bitchin sound system in the house growing up. I remember him playing discs (not compact, but the size of vinyl) way back in the day. Then we had CDs way before most even knew what they were. Well he passed away a few years ago and I've come across some of the stuff... Like others, I inherited my dad's carver stack: C-2 preamp, M-1.5t amp and m-200t amp. They haven't been used in many years. I'm wanting to hook up a Pioneer record player to listen to vinyl in the house. First, some guidance on connecting everything up would be great. Can I use both the M-1.5t & the M-200t? Or is it one or the other, not both. If that's the case, which do you suggest? Next my volume control seems corroded. I've tried spraying CRC Electronic Cleaner and turning the knob, but it's ineffective - lots of cracking and R speaker comes and goes. Should I try something else? Is there a replacement? Thanks for the help.

You need to test TP 1 to TP 2 - NOT to ground… same with 3 & 4.

TP3 or TP4 to ground is 5.1vdc. TP1,2 to ground is 100mvdc. I checked all of the outputs and they test fine. I’m thinking another transistor on the board ?

I do too. My wife and I go to Modernism Week twice a year in Palm Springs. Architecture, decor, fashion, cars, etc. Very interesting and amusing step back in time.

I love MCM.... someday I want to create a listening room that is all Mid Century Modern decor.

If you have 5.1V between TP3 and TP4 ....... your amp is on fire.

Your great music posts make me smile all the time. Good stuff!!!

☝️ Now that made me smile!

I checked all of the output transistors Q119-126 as well as Q118,119,109,110,116,117. All test good

Checked MV at TP 3,4. Have 5.1v. VR 102 had no effect. Should be around 6mv. Looks like an issue to me

Welcome! I found that Carver Silver 7t amps powered my Infinity Kappa 9's quite nicely. I've moved on from the Infinity speakers, but not the amps. Carver amps really like Polk and Infinity speakers.
