Bobby1970 1,352 Posted February 12, 2019 Share Posted February 12, 2019 Welcome 69Chevelle, am also new here, I'll keep reading your posts as I also have the same gear but don't have the time and budget yet to do the mods, its great being here.. 10 hours ago, Turbo said: Welcome aboard @69Chevelle!!! I bought my C-1 & M-1.5t some 15 years ago, rebuilt the M-1.5t last year and did the BillD to my C-1 shortly after the M-1.5t repair. Has been an eargasmic adventure ever since ?. I posted my repair in the amplifier, amplifier repair, M-1.5t repair as seen below: You won't regret the M-1.5t rebuild. It sounds fantastic now. Was very grainy and harsh before it died. But is silky smooth and fabulous now. That BillD C-1 will blow your mind too. Turbo Hi Turbo, I would like to do the same with the M-1.5t I have, how can I see the thread you posted when you're doing it? Thanks.. Link to comment Share on other sites More sharing options...
Community Admin AndrewJohn 8,030 Posted February 12, 2019 Community Admin Share Posted February 12, 2019 Welcome! You are on your way to full-infected OCCD. Say, one suggestion..., start a new thread on your project in the Amp or other section of the site. That way, your project, and pics, and all the words of advice and wisdom, will be easily found by others. The welcome thread is still really valuable, too - just thinking of your project going forward. Welcome! Love the m1.5 too. Link to comment Share on other sites More sharing options...

(The big brown ceramic caps circled in the pic below) Those are notorious for cold solder joints and you may find it clears up by tapping on them. If so a reflow of solder is in order. I didn't have any problem with C1 on mine, but others here have reported problems in theirs. So I went ahead and reflowed the solder on C1 for mine below just to be safe. I also re-flowed all of the solder on both amp cards on both sides as circled below. That is likely your intermittent channel problem. Regards, Turbo Turbo, Jeffs you guys are on point, I took some time last night and took the lid off the amp and gave things a look, went ahead and reflowed the both C1 and bingo the intermittent channel came back to life and both seem to be working great now. This was just on the bench, so now next step is to hook it all up and give it a listen. I haven't listened to this gear in 8-10 years so needless to say I am excited to have it working again. Step 1 was to get it operational and now I can start the mod program on both units. Thanks again for your help, loving it here already Edited February 13, 2019 by 69Chevelle typo 1 1 Link to comment Share on other sites More sharing options...

Consider changing out the elecrolytics, you wont regret it. In my experience the dual caps almost always have issues given their age, the large caps are next, followed by the smaller ones as outlined by @Turbo The duals are a challenge to remove and require patience. Sounds like you have the tools and skills ... but take your time with these. Working inside a 1.5 involves many obstacles, but still fun. Link to comment Share on other sites More sharing options...

I can't wait to read about your mod progress in the amp repair and C-1 mod sections. Please start threads there to document your adventure for all to enjoy! You won't regret that BillD mod to your C-1, it is stunning. There are many great folks here to assist you if you have any problems or questions.
