Thanks guys. I didn’t even have a chance to look at it today after recovering from last night, then spending time with the family. Flying home in the morning, pops is going to crate the amps real good and we’re going ro ship them ground this week.
Up early this morning to head to the airport. Had a few minutes to pull her top down and take a few nudies. Looks like the filter caps and a few on the board were replaced which is what the seller told me. No time to make any adjustments though. Pops is going to crate them up this week along with the Prisma and a pile of records for me. Just a PITA to take on the flight with me. I’ve got lots to do anyways, Lee sent me a DCP board for my 400, also a light board kit ans some other goodies, speakers to move and new builds also. Lots to do!
So I pressed the 700 into service since Linda’s injury. All was good and I wasn’t gentle... now one channel has distortion at any listening level. Switched the power off and going to bed. Not complaining in the least, these are old amps... maybe I should ask the pimple face kid at Best Buy about a decent replacement? But I think you guys got two amps to coach me through now...
Slugged this 70lb beast in, wired it up. It’s only better than the PL 700 in the sense that it works rn. In this configuration it should be 1200wpc. I can’t tell that it’s any more than Linda or the 700.
Yeah she was fairly warm... you could still put your hand on the heat sink. These speakers are the 4 ohm woofer section... she didn’t high temp trip though. I had let her cool down then put on “one last” bass intense song loud, but not “abuse” territory and she popped.
As far as the 700 goes and correct me if I’m wrong, but I figure I can check the outputs for shorts on the bench, remove the rail fuses and DBT? If that fails then disconnect the transformer, test and work through the power supply until I find the short? I bet it’s a nasty short as the fuses snapped hard.
I think I’m going to start into the 400 today, remove the bad channels outputs. Can’t be without any working PL gear for too long...
