That machine was dropped!! It needs WAY more than a new pinch roller!

So,... I hate to take this tact with you, 'cause you've really made a great effort,... but
"I gotta go digital 'cause analog's a headache" is an all too common thing that's heard around these parts,... but was so unexpected coming from you!!
See,... back a bit I remember most "trusted" members urging you to get a Tascam R/R recorder, mostly 'cause they're sturdy, run well & are easy to fix with parts that are readily available. But no,... you had to have your Otari, 'cause it's "more-pro" than Tascam. So,... you got your Otari,... then another one to fix the first one,... then they both don't work up to par,... and what did you get in the end??? A "Pro-sized" headache!! You can't say you weren't warned!
So, now you wanna "go digital 'cause analog's a headache",... and you'll find no end to the support you'll get on this board for that decision,... but all I can say is,...
"Good luck & C'ya!!"
PS: I'd not touch that deck in the auction, (above), as it's another typical Otari that's been rendered to junk, just before it was listed on Ebay. You've gotta be off your rocker if you buy or recommend buying the recorder in that auction!!!
'Spat,... it's nothin' personal,... but we've had many discussions on this board about what to get/not get,... and I've always said I've never seen an Otari that wasn't junked out and trashed, & in the big scheme of things I'd not touch a second hand Otari. I've seen too many of them that were just flat out junk. And that's not one or two oddities in some podunk town. It's many Otari's I've seen that were excessed from real Hollywood studios. JUNK!! ALL OF IT!!!
Again,... 'spat,... it's not personal, but you go against "general wisdom" when you ask your questions, and you seem to get deeper and deeper in the muck. Although, I must hand it to'ya that you've hung in tough with many troubleshooting problems with an effort and tenacity becoming of a "Pro".
Please... have a nice day!
PS: Don't listen to me. I'm not a "Pro". Only listen to those who claim to be "Pro".
