I'm going to have a look inside this weekend, so I'll check that out

HI-My Dokorder 8140 4 track, doesn't playback or record on the front 2 channels- Is this a case of dodgy transistors?, I had similar problems with my Akai and new transistors fixed that :(

:(After replacing all the faulty transistors, I now have a fully functioning deck; however the illumination in the logic control push buttons do not work, any ideas?-

Well, I got around to replacing those defunct transistors and I now have sound and recording- My main worry about the reel motors running at the wrong speed has not materialised : which although I'm overjoyed about, I don't really understand why!-Only one problem left to fix- is the logic...

Just a quick update, I've near enough got all the parts that I think I'm going to need to fix the 625, then I'm browsing through Reel to reels on ebay and spot a UK spec 625 for a bargain price that's working-but needs some TLC- I just couldn't stop myself from hitting the "buy it now"!!-Luckily...

I think you may be right about the Hz issue, at least all the mechanics seem to work properly-I've partially stripped the deck down since my last post and can see no damage to the pc boards etc., so I'm definitely going to replace the 2sc 2240 transistors on the pre amp board (which is what has...

Akai GX 625 Thanks for that- but that is the problem- because this is a North American version, it hasn't got that switch- all it has printed on the cover is AC 120V 60 Hz 150 Watts-Since my last post, I have just got a 230V to 120 V stepdown transformer and connected it up and all the reels...

Thanks guys for your thoughts on this problem. Like most people I originally thought only about stepping down the voltage without realising that there could be a potential overheating/speed control problem with the reel motors- What makes it worse is that I also have an Akai GX 630 but this one...

After a lot of investigation, I've been told that the 50 Hz- 60 Hz problem arises because of the way that power stations generate their electricity- Apparently, the easiest way out for me is to buy a 12 volt DC input to 110/120 volt output 60 Hz transformer ( of suitable wattage) made for the...

I've seen an ebayer in the US advertising TEAC NAB hubs for a good price-Can these be used on Akai decks. I'm worried that the tape path will be slightly different

Thanks for the response- I agree that the capstan motor is not the problem and I think I'll bite the bullet and get a 500 watt stepdown and see what happens-I still can't make out how Akai can incorporate cycle change in some of their decks as a matter of course- (and other manufacturers have...

In the Akai user manual it states that with the models where the voltage is adjustable -Quote "CYCLE- As the unit is equipped with CPG; AC Servo Motor, cycle change for capstan drive motor is not necessary; The following instructions are just for readjusting reel motors torques according to...

This is my first post and I'm hoping for some help- I've aquired a Akai Gx 625 (USA model) which only has a 120 volt 60 Hz mains input- I want to run it in the UK- but so far all the step down transformers I've looked at, convert our 230 volt 50 Hz down to 120 volt 50 Hz. I gather that the...
