Name this recorder
A hard one from this photo I think. Some people may recognize the make but the model (is not common) is more difficult, but the tape transport control buttons may be a give away for those in the know.

Re: Name this recorder
I'd guess either Akai or Sony, judging by the heads, I'd go for Sony.

Re: Name this recorder
Changed my mind! I think its an Akai, because of the VU meter design.

Re: Name this recorder
Yes Akai, I also should have said that normally it all is vertical, the tape deck section is just horizontal because it is out of its case for fault finding.

Re: Name this recorder
My guess is an Akai GX-286DB.

Re: Name this recorder
Spot on Lawrence, good detective work. It has quite distinctive touch sensitive tape transport control buttons which work very well.
I have 2 of them, the first one arrived with quite a lot of serious corrosion internally on the metalwork, which took some tidying up and had numerous noise issues caused by bad transistors. One remaining problem I need to resolve is that the automatic reverse modes do not work, have spent quite some time investigating going round and round without be able to locate the problem so far. The second one is extremely good condition with no problems (a rarity I would say) . David |

Re: Name this recorder
What are the voltages telling you for the no auto reverse fault? I hope you have a clearer schematic than I have.

Re: Name this recorder
Schematic is not great, the voltages are a fuzzy red, I had to enlarge section and print to be able to see somewhat better.
I have not looked at it for quite a while so will have to revisit my notes to see what sort of results I got, on paper it looks simple, the first 2 transistors (seemed like both of these are not switching, when the single Sense pole is grounded) on the System Control board have been replaced with no change and all surrounding components checked out OK. I know it is the System Control board at fault because swapping the boards over between the 2 machines swaps over the symptoms, i.e. good machine then does not work and bad machine then does work. Physically it is a difficult board to access/monitor. David |
