Hi Guys!!
Today was time to get this big beast working properly!!
You may remember I mentioned in the original post that the cassette deck motor servo was completely inaccessible without somehow taking it apart & removing the tape mechanism & running it while open so the servo pot could be reached
Yeah, a daunting task indeed!!
The psu is mounted in the rear casing along with power amp & lots of cables between the two, the tape deck had to be split from it's pcb to access the flywheel due to a somewhat slow & unstable playback
I then removed the belt & flywheel & found that the flywheel bearing was bone dry & the flywheel didn't spin freely at all - drop of fine oil on the capstan shaft sorted that problem out
All the rubber wheels & bits were cleaned while it was so apart & I then temporarily screwed the tape deck pcb back in place still pondering on how I was gonna run this thing all in pieces
Around half an hour later it was time to power it up after I only connected the minimal amount of cables from the deck to the power amp which also had to connect to the tape pcb!
All this balanced up using tea towels & towels to avoid boards touching chassis or other boards - this bloody thing has an entire pressed steel chassis, no wonder it's so heavy!!
Headphones already plugged in - speaker outputs not connected & anyway, phones are easier - placed a tape in & hit play................f**k me it was playing with a buzz or 2 due to earth & screening wires not plugged in & of course, really bloody slow
That was no longer a problem as I had access to the servo in the motor..........in no time the speed & azimuth were fine adjusted & the battle to reassemble was underway!!
Took my time & did it slowly there was a lot to do putting it all back but after a small battle or 2 with reassembly it was time to press play...........
& Viola!! All sorted & a very happy owner - I didn't want to just leave it & knew it was going to be a challenge but holy shiat, this was a labour of love, wouldn't take this job on for anyone else, it's a pig to do & the risks of running it open like that is no picnic
Quite a lot of bad language lol & a stressy job no question.........
Long live the Maximal 3040
