|
|
Bought this deck from a place in the UK, its got the 240v power cord and obviously runs on 240v. if the internals of the deck do not have a switch for the voltage, how hard is it going to be to convert it to US 110v?
It comes sometime today so I wanted to get an idea of what this entails. I really dont want to buy a voltage adapter, and if I do modify the deck I would prefer to keep it looking as unmodified as possible on the outside

Sometimes there's a tied off wire on the power transformer primary with the 110 volt tap. If there are only two wires out of the primary of the power transformer, you'll need to find a 110 volt power transformer. hopefully there's not too many secondaries coming out of it.
Or.. can you fit a small 110 to 220 volt transformer within the deck?

Not yet sure Curt it will be here anytime today, should be within 2 hours or so. I hope either it can be converted or it is ready to convert from the factory. The deck is in mint condition which is why I bought it from the UK instead of US ebay.
Will let you know what its got when it gets here

If it's the Asia model then it has a voltage selector switch. If it's the UK/Austrailian or European model then it uses a different transformer then the US and Canada models. No selector switch on these.

Just got the deck, its a full on UK model, nothing but 230v input lol
So what do I do to convert this thing?

Actually checking that out right now, no wires actually coming from the transformer, its soldered to the bottom of the board so I have to take it out and see
Will post back with what I find

Wrong connection, its the plug end that has 2 large rectangular pins, then one more large rectangular pin, its about a 2" diameter plug

OK, well there are others on eBay, either cut the plug off and put on the one that will fit this adapter, or I'm sure the correct AC transformer version is there on eBay somewhere...

Bought a Denon DRS-640 off ebay thats all banged up, but its US, it works, and has the transformer and power cord I need, and it will still all be denon. got it for $50 shipped so it was a better buy

OK, judgement call here. A super nice deck, but is it all that compared to say a Nak 3 head unit?
Not trying to flame here, but I'm not familiar with that Denon model.. Seems like they go for big $$ though..

Not sure yet Curt, but from what I read the DRS line of denon Cassettes is their top of the line series. Theres the DRS-610, 640, and 810. Obviously 810 being the top of the line model.
Unlike the other DRS decks (which also had the horizontal loading tray) it has 3 heads instead of 2, and a 4 motor transport. The only belt I noticed in it is for the opening/closing of the tray.
Its a hefty unit, about 12 pounds or more I would say, looks to be quality built (as most denon stuff is). The only thing left to do is listen to it which I cannot wait to do!
As for Nak units, never heard a nakamichi, but from what I've read over on tapeheads forum is that Naks are the best.
Then again, I dont think many of them have had this model Denon deck or one like it.
Lets put it this way, it better sound good dammit, I have $263 into it with the 2nd parts deck

Cool, let me know. I have a middle of the road Nak, 3 head, probably a bit lower end than yours. I love that deck, but now it appears that one channel is dead in record mode.
Before that I had an Aiwa 6950 (I think that's the model). Paid $400 for it back in 1981. It was the first 3 head deck I owned, and the first cassette deck that I didn't hear the difference between LP and Cassette. Both those decks have seen heavy use, and the Aiwa is now toast, as the mechanism is impossible to get into. I got my money out of it though. It was the mid 70s deck with dual analog VU meters, one for RMS and one for peak readings.

Well I got the deck to part out the transformer & power cord, I swapped the transformers, and noticed the new one only has 2 pins on the primary vs 3 pins like the old one.
needless to say I went ahead soldered it all in and changed it over, and no power....
So I assume something is not right??

I've got it! I had to add the 3rd primary because the deck I removed it from did not use that, so denon cut it off. I added it and voila!!! we have a working mint DRS-810 that is now a US version
WOOOT!!!!
