Need PS Audio PS IV schematic

[JTM745i]

Greg Stewart,

Im new to this board and it seems your a a google account of Vintage Audio?!
I could as well use the Service Manual for the PS IV Preamp please as I wish to cap mine
and having a list makes it so much easier I’m not a pro but been repairing Vintage audio for 30 years,
mostly Carver as there seems to be a lack of Service manual for PS Audio such as my Power amp one with Linear and pre amp, recently recapture and upgraded my Carver TFMx Amp what a …… to take this think apart,
Sunfire don.t touch only Bill in WA has the service manual not to mention all caps are Chinese, though
just because I Love my friend I recapt his Sunfire Ultamate Receiver 160 caps only I be so stupid LOL
Mother Board, Power board and main amp board.

Anyhow looking forward to intermingle here and who knows maybe to help others as you do.

Hope you get to read this.

Thank you kindly in advance.

LOL, not associated with "Vintage Audio" though I have & have had a lot of vintage audio.

I guess it goes with being a vintage DIY audio buff!

PM me your email, I'll get you all the PS Audio info I have.

Greg,

Please forgive me I meant diyaudio lol

Ones I get approved to be able to PM here I will do so.

On another note, would you by any chance have anything in the Infinity Rs0.2 speakers?

Thank you kindly Jens

I still have the preamp, actually I have 2 of them. The hand drawn schematic not the service manual I had (that I got from Greg) almost a decade ago, was on my pc that developed a major case of bohemian hemorrhoids died few years ago. I lost everything on the pc.

Have not used the pre amps in many years!.

Regards,

Art, sweet, got an extra push button?
when I took them apart to detox the switches and one spring just said good buy.
PS audio send me an Owners manual it has a little schematic not match though.

Jens,

Nottaprob on the mis-association.

See if what I sent to you via PM works ok.

I may have some of those pushbuttons if they are what I remember, post a picture.

& sorry, I don't have anything on those speakers

Crappy picture I will take some tomorrow,
Inside they have a u shape bend plates with springs behind them, by the design I wonder if my various contact issue is even Oxy related.
That be awesome, are there any good upgrades beside maybe adding 2-Wima for the filter caps?

 

[JTM745i]

Greg,
Here you go, the more I review this design the more I wonder if the issue with these switches is rather bad springs than Ox.

See if this helps to identify

These are a pain to put together, you can see on the one picture where the spring on the right is missing.

One picture assembl.

 

[Greg Stewart]

I'll look & see if I have one here... It might be a few days or more, sorry!

No worries, greatful for your help.

 

[JTM745i]

Hi Greg hope you are well?!
Any news on the switches and or springs?

 

[Greg Stewart]

Sorry. I'm ok, but an unexpected water heater replacement, moving all the stuff I had in the way out, & slowly reorganizing (&/or trashing) has kept me busy. No estimates on when yet, keep on me!

Greg I‘m sorry to hear that :-(
Hope your loss was not to big.

 

[Greg Stewart]

Thx. Caught it just in time before serious leaking. Had to clear out utility room into already overcrowded garage to have it replaced, slowly getting things re-organized / re-stored and/or trashed if no longer needed.

Will keep watch for those parts.
