Check under the hood for a jumper switch. If that's not there, it is wildly impractical. Maybe an external transformer would work better in that case.

I noticed you mentioned your 'Technics gear' in your last post. I've just scored for a timewarp SU7300K for £50! Comes with everything as new - orginal box, schematic, manual and even original spare fuses. I'm pretty excited about this one as I'm becoming quite a fan of the old technics stuff. 

 

Heres a pic from the seller (could have went for the tuner as well but I've really no need and it would just be for decor)

Processed By eBay with ImageMagick, z1.1.0. ||B2

Man, I love those black face almost as much as the silver faces!  Sometimes more.................like the Pioneer 5390 (think I have that number wrong) I was lusting over last weekend.

 

Congrats LugBug - nice addition!

It's easy to peel off, as the glue holding it in place is old and dried out. Just go slow so that you don't crack the tuner dial. As for the diffuser, I just used printer paper :D Couldn't even tell the difference. If you're replacing the lamps with LEDs (which I HIGHLY suggest), there's no need to worry about heat.

Well I was gonna upgrade my Marantz 4270 next and peeling off the dial face seems like the best option because it's screwed up in there. Yes putting LED's in it. I don't know about the Bi-Pin lights. know anyone on ebay that sells those as LEDs? 

whenever I search it, I get Raspberry Pi crap...

Cheers bud. Yeah my little experience with Technics is very positive. I'm keen to hear how this 1977 amp will stack up against my later 1981 'new class A' model. The new class A amps were very popular and faired well in the hifi press. I remember my Dad buying one at the time.. I remember it well because he told me that it had a little computer built inside! That seemed wild ha, researching now I realise it was the V505 and it had this :-

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), default quality

Cheers bud, yeah I do like the black look. The problem was though, by the mid 80's everything went black. Black with as many knobs, buttons and gadgets as poss haha. I think the aesthetics went down hill for sure at this time, and it became more about boys toys and the latest gadgets over style and arguably substance.   

But as we all know here, there was a golden age before all this happened and the above amp is defo in that bracket. Meters! I don't think the later designers appreciated how much we like meters!!

On the Marantz units I have worked on (2215, 2215B, 2220B, and 2230) there was no need to peel anything.  After taking the top cover off the lamp assemblies were accessible from the back.  Just had to remove a couple of screws.

I'm thinking of parting with the Marantz 2240 that I got from Skylab - it's not refurbished but sounds very sounds good, with crackly knobs when they are turned.  The local shop wants $150 and 12 weeks wait time to clean it up, and I just don't use it enough to do that. It drives my HE-6 and HD800 quite well, but I've been using the HiFiMan EF6 these days.

 

Is there anyone local in Colorado that would clean it up for a fair price, or just take it off my hands for a fair price?

Have you considered a Deoxit treatment yourself? Easy to do.......
post #11888 of 16770

^^ Exactly, if it 'sounds good' then don't fix it. A quick Deoxit will take care of the noisy controls and can clean the sound up too. 

post #11889 of 16770
No, I don't want to take the cover off and I have way too many amplifiers to listen to them all right now. If it was my only amp that could drive speakers or a HE-6 well then it might be worth the effort. I'm at 60% normal lung function, so I also don't want to deal with the fumes. I probably should just let it go.

Currently in the 800C,  I've got late 50's Sylvania short black plates in the phase inverters and 60's Matsu****a with 45deg getters in the preamp.  Liking the sound now, but curious what you've discovered in your tube rolling.

Lol I haven't done any tube rolling surprisingly. It came with the stock tubes which happen to be Telefunkens. So I left them in place. That's another thing I like about vintage tube gear(provided they test well). There are no cheap Chinese tubes to worry about getting rid of. But I must admit, I have contemplated going for sylvannia blackplates to warm things up a bit.

Wish I lived near you. I'd do it for you gratis and be happy to do so.

Good 'nuff!
Three of the four positions in the 800c had original smooth plate telefunkens- very smooth mids. The sylvania blackplates added just a touch of warmth which was negated by the matsu$hitas- sparkly extended treble, detailed, crisp and focused imaging. An overlooked tube IMO.

Picked up this Kenwood KR 9050 today, local purchase.  Everything works as it should, looks and sounds fantastic.

Interesting. I've never heard that brand of tubes before. I might have to try one out one day. So the sylvannias did add just a touch of warmth. I think I may have to add that to my saved list.

Wow, stunning. That's a beautiful receiver, and the best kenwood ever made imo. You scored big!! Congrats.

Beautiful! There's something about levers on vintage iron that just makes you wanna... (don't make me say it! :tongue_smile:)
