Technics SP 10 Mk II a


It's been suggested that I recap the power supply of my SP 10. One person also mentioned replacing the caps inside the TT module at the same time.

I could pay to have this done, but could as easily do it myself. What caps are appropriate, where do I source them, and where can I find schematics to help determine the appropriate locations and specs.

Has anyone done this themselves? I'm experienced with a soldering iron and have some time available, as well as being attentive to detail (not re-tentive).

Would the better part of wisdom be to have it done by a professional at $85 an hour, and if so, whom do you recommend?

with appreciation,

In your last thread you were given the names of two folks who've done extensive mods on their SP10 Mk II's. Have you contacted those folks? Seems to be they'd be great resources to answer those questions directly:

Albert Porter
Steve Dobbins

Someone recently pointed out to me that many of the Audiophile caps are produced (to spec) by the same company and labled with the Audiophile moniker (Auricaps, V-caps, Infinicaps, etc). Can't recall the name of that manufacturer...TVI...TMC or something like that. Unless you want to put down some serious coin for something more exotic like Mundorfs or Audionote. I think there are quite a few caps in that PS, aren't there? Not all techs are $85/hr. My friend is having his SP10 MK II supply recapped locally by Roger Hug (Seattle) and I'm sure the rate is pretty reasonable, but patience is necessary as Roger stays pretty busy. Perhaps my friend will catch this thread and chime in, though I know he hasn't got his PS back from Roger yet.
I just recapped a mkII deck and power supply. I used Nichicon electrolytics for the power supply, (no special considerations)and a Panasonic series for the deck that was recommended more than once in forums for it's low ESR (equivalent series resistance). I opened things up to make sure of cap type, value and location. Be gentle with desolder/solder on the PCB's.

Manuals are available online that include schematics.

Agreed, the above mentioned folks are "in the know".
Jax2 named a bunch of boutique film cap-makers. You only need to replace the electrolytics, not the film caps unless there is a specific problem. This is because your tt is pushing 30 years old, and this is beyond the normal life span of an electrolytic cap, particularly if the unit has been in storage for a long time. The film caps are likely to be OK. All parts other than caps are typically good or bad. But lytic caps can cause subtle problems, because they go leaky before they completely give up the ghost. The term "leaky" means they leak DC voltage. A leaky lytic can damage those ICs that would be hard to replace, if it could be done at all. I think Albert used Black Gate caps in his outboard PS, but I heard that by scuttlebutt, not directly from Albert, so I don't know. Anyway, modern electrolytic caps are better than anything that was available when the SP10 was built, so I see no reason to spend big bucks for fancy Black Gates (even tho their low voltage line is relatively reasonable). I used Panasonic. Their best low voltage line is called "FC". For the few higher voltage caps, I recommend their TS-ED line; I am using them in my amps and preamp and they sound great, if that matters in a tt. (Nichicon, which Strathorncat recommends, would be great in this application, too.) I bought all the caps needed for my entire SP10 (about 20 capacitors) for the sum total of less than $20 from Digikey. You need a service manual to find the values needed and their locations. There are about 8 electrolytic caps in the outboard supply, and I would replace those first. That is very easy to do yourself. Even though I do a lot of DIY, I am not comfortable with solid state, so I had the on-board lytics (meaning the ones mounted in the tt chassis) in my Mk2A replaced by a pro. The charge was nominal and it was worth it for peace of mind and for the fact that he calibrated the on-board circuitry as well.
