Vintage DD turntables. Are we living dangerously?

Hi Lewm

Yes, I believe you are correct. Chris said he replicated the IC with 7 components? That is about how technical I got or understood.
He did mention the Pioneer circuit board was the simplier of the three dd tables he has worked on.. The JVC and Demon were crowded and complex relatively speaking.

Yes Henry, excellent work from Chris indeed and thoroughly recommend him to anybody. Thanks.😇

And yes gents, I will have Chris take a look and replace all the caps for safety. 35 years service is pretty good and they may last another 35, but as you said if they fail due to age it will be good to safeguard it not have it happen.

I have asked my mate from Japan first to see if he has a Exclusive P3 Japanese service manual, but I doubt he has one, especially since Pioneer still service all Exclusive products in Japan.

Cheers and happy listening to all with their timeless Japanese DD tables 😁

Just completed a complete refurbishing / rebuilding of a Micro Seiki DDX1500 for a customer. These old machines are truly excellent. Did a speed check with the time line, over an entire album side the dot did not move from 23 feet across the room !

A nice little upgrade I did to was having the inside of the platter sprayed with Polyureah (Truck Bedliner), this silenced the bell like character of the platter nicely.

Good Listening

As Halcro and I know, there is NOTHING in turntable land quite as complex as a Victor TT101. I haven't seen a P3, but the Denon DP80, Kenwood L07D, Technics SP10 Mk2 and Mk3 are as simple as a belt-drive, by comparison to the TT101.

Amen....😱⁉️....unfortunately...😬

By the way Lew....are you actually listening to a 'working' TT-101? 🎼🎵🎶

Nice use of emoticons, Halcro. One emoticon is worth a thousand tears.
My TT101 is working, if I leave it powered up at all times, and if I don't move it, and if I run it at least once a week. With those stipulations, it's "reliable". I have heard it play music, but my new problem is that there appears to be a short within the UA7045 tonearm wiring, such that I have no right channel. I need to change the tonearm on the QL10 plinth. Interestingly, the Fidelity Research FR64S has a requisite spindle to pivot distance that is compatible with that of the UA7045, so I should be able to pop in my FR64S in place of the UA7045.
I will do that one of these days, when there is no other "project" in the way. Also, I am enjoying the Beveridge 2SW speaker system so much that I tend to want to listen to music when I do get free time.

Interestingly, if the TT101 gets balky, usually after I have not used it in a long time, the cure is to whack the (front) side of the plinth nearest to the control panel of the TT101, with the palm of my hand. Very unscientific but works a treat. I am very convinced that there is a bad switch or a loose connection between switches that is to blame for the finickiness of the table.
