NAK 1000 ZXL (third one) in da' house

Well I came across another one. From original elderly owner but no known history. Serial number is 3xxx so a mid to later model one with the newer PCBs. It has issues but hopefully they can be resolved unlike my second one which I could never figure out completely.

The first ZXL I owned was a late model one with SN 42xx and I was able to get it to work perfectly. It was a true glory deck that I wish I did not have to sell a few years back (but that is another story). http://www.audiokarma.org/forums/showthread.php?t=467549

The second one was SN 21xx and it had the older PCBs. I did the standard OCD repair and Electrolytic replacement along with some solenoids and a few transistors. Never did get it working right and the auto allignment logic just was confused. It was over my head so I sold it to Perry. I'm not sure if he ever got it resolved? http://www.audiokarma.org/forums/showthread.php?t=539603

Anyway, I could not pass on the deal for this one as it is cosmetically quite good and the transport and heads appear to be in fine shape. Tore into it this morning and it is clear the last person in there worked in the Nakamichi factory (a good thing).

I did the basics on it, clean and lube transport, deoxit all switches and controls. Plugged it in only to find it has similar issue as number two. I was hopeful because it is a higher serial number deck but alas...

Why do we do this to ourselves? Oh well, I have to go read my ZXL notes...

At least it is very clean inside and out...

By the way, I can confirm that SN 30xx has all the latest PCB boards (like my SN 42xx). It is hard to find the transition SN data on these decks. These are the same boards used on all Limited ZXL decks.

CPU B PCB is 3rd version (last version)
Main PCB is 2nd version (last version)
Playback amp Dolby NR PCB is 2nd version (last version)
 
I need some PP caps for this project. I can't seem to find these last few in the usual places (back ordered for months).

I have a post in PT looking to buy some but I thought I would also post here in case someone may have other ideas? I also need one Electrolytic I cannot seem to find.

also need a 220uf 6.3v low leakage electrolytic. (Nichicon KL would be great)

any ideas?

I have a 1000ZXL deck I bought new but will have to look and see what the serial number is, EX wife threw out all my cassettes so I have nothing to play on it the lights still all come on though.

It's probably no good. If you want, I will swing by and take it off your hands :D
