388 schematic that’s not the crappy scan everywhere?

Post by Darlington Pair » Thu Apr 02, 2020 6:05 pm

Does anybody have a legible schematic for the Tascam 388? The record play relays are out for channels 1-4 and I can’t read the schematic you can find everywhere. If I move a card from 1-8 they still don’t work so it’s something common for the first two cards

I have the printed manual but I don’t think I have access to a legit scanner...still a phone photo may not be bad. Any idea what page you’re looking for?

Definitely the stuff for the Rec/play pcb (which I just recapped two of them, not the two that went out... one in each bank because I was having record problems) and I probably need the pcb with the record arm switches. It’s hard to see what goes where with the signal to flip the relays.

Thanks so much!!!!!

Is this helpful? I can zoom in on this enough and have it be reasonably clear...

It’s a little late for me to determine what page you need for the record and switches...if you have any way of figuring out the page number that’ll make it easier for me to find what you’re looking for..(tomorrow)

That’s awesome!

Thanks!

Looks like hidden in the blurriness of 4-3 Monitor PCB ASS’Y I can kinda see the record arm switches. That and the one you did already should be great.

Okay cool. Will do it when I get home.

At my old job I actually had intentions to scan this manual since I had access to a great pro scanner but never got around to it. Maybe they’ll let me come in some night and do it.

Nice!

Looks like my problem is probably the mc14011bcp. I hope I have one around the shop somewhere, I’m so ready to use this thing.

Hey, thank you so much. I forgot to update. I ordered the three Rec/Play cards that were on eBay, I recapped the ones I have, but the problems were deeper than that because all my dead channels were still dead. I’ll rebuild them soon, but I just wanted to get recording.

My problem getting the relays to kick on was indeed the mc14011, I found one and everything is recording wonderfully. Now if I can just figure out why ch 8 only wants to record the line in (didn’t even want to bounce), but it’s not a problem that’s keeping me from working so I’ll deal for a little while.

Good to hear. I was hoping you weren’t asking for more pages, I should start up a patreon for all the 388 questions that come here :twisted:

I'm going to do a GOOD scan of my 388 manual & service stuff so I have it as even when you buy it, the scan that comes with the manual is the same garbage one everyone has.

Once I do, i'll share it.
