Wow... As in there's nothing else that can be said... What an incredible project!

Nothing quite like overkill
Excellent work !

What sort of oil do they use in the bearings?

I have a some of the stock oil SY, if you want some to check out.

Dave C, et al.: What approach would you take in regards to electrolytics on an NOS unit that's sat for ~30 years? Summarily replace all (my inclination)?

 

[Dave Cawley]

If there is no sign of leaking or bulging, and if it measures OK, then I would leave it. If you must, do one or two at a time.

Regards

Dave

What's the reason for not replacing all?

 

[Dave Cawley]

'cos if you make a mistake, it will be difficult to trace. Hence two at a time.

I understand that. What I mean is, many folks recommend summarily replacing electrolytics of this age as a matter of good practice. You don't, and I'm wondering why; if there's a reason aside from 'if it ain't broke, don't fix it'?

Yes, on the SP-10 MKII there are only three capacitors that need changing, all others are just perfect. Changing them all needs thorough testing afterwards, so why bother ?

Sometimes a blown capacitor takes with it to kingdom come other parts of the circuit that can be hard to find...like vintage ICs...
An electrolytic that is 30 years old can give up anytime...
Great design by the way!And i mean all of it!Table plus turntable!

 

[Dave Cawley]

That isn't going to happen in a SP-10 and all the IC's are available. Buy hey, go change them all if you want, no one stopping you !

Dave

 

[JP]

I know there are IC replacement options for the MKII, but my NOS unit is a MK2A. I haven't been able to source all the ICs for that one.

Back together and running smoothly -

Here's the arm for it -

Next, remove the guts from the other one, send it to Einric_99 who is making the plinths, then get it repainted.

No underscore on my forum name....
Just my email, LOL
I look forward to completing these for you.
The ebony veneer will look fantastic.

 

[Dave Cawley]

Looks great, what was the metal finishing process ?

Thanks

Dave

 

[Coasttocoast]

Great work. Looking forward to seeing the finished product.

I had the opportunity to talk to my brother-in-law Steve today, and got some clarification of what was done. The specifics are as follows;

Abrasive wheel to remove the old paint and corrosion.
Etching primer for aluminum
A 2-part 'glazing putty' was used to fill the deep bits
Then it was normal autobody process from there -
Prime
Sand
Paint
Clearcoat (a bit of flattening agent was put in the clear to cut the gloss to my specific request)

looking really good. I admire your ability with electronics.
I'm using a Graham 2.2 on mine. Happy camper.
I look forward to seeing your final product.
Excellent stuff.
