Power cord connector for old Wurlitzer piano

Hello,

I am going to restore an old Wurlitzer 145. I don´t have the original power cord and before I fit a standard IEC connector on the piano I thought I´d check if someone here has an original type connector or cable. See picture.

Thanks,

Gunnar

Added pic.

I am also curious, I have an old Westinghouse radio/phono player that
uses the same power input jack.

I can carve up extension cords to work, but I'm looking for a decent
appearing replacement.

I have found that a 2 prong extension cord can fit pretty well.  I'm not sure if that was the original intent though. 

I think I have some versions of that cable where the plug body is metal, and provides a ground contact.  No spares though.  You should be able to find surplus somewhere, or another round type that will retrofit. 

Thanks for the replies guys!

Hi Gunnar,
I put a standard IEC connector in mine.
I had to file around the existing hole to make it fit. 
I know it's not strictly vintage, but then again it gives me a safety ground and beats looking high and low for a vintage connector.  I looked and didn't find one.

The 145 amp is a little bit noisy, but the tone is awesome. 
I've been told it's the nature of the thing...
I'm no tube amp specialist but I've built a couple of amps and reverb units, preamps and LA 2As that are dead quiet.  I tried every trick in the book on the 145 and rebuilt the amp twice, thinking I'd screwed it up somehow...
Anyhow, the noise is part of the vibe and it sounds super great recorded.
I'm just giving you a heads up because I had certain expectations when I set out to rebuild the thing (not that I'd ever heard a dead quiet 145) When I couldn't get there I kind of freaked.
The noise level is actually pretty low, but easily loud enough to obsess over.
Remain calm.
The 145 truly taught me to understand the difference between noise on the test bench vs. noise in context with the music.
   

Hi Sleeper,

Thanks for the reply. I will do the same with the connector. I have not really started with the amp yet but it is good to know that I should not try to rebuild if I hear a little noise. When you say noise, do you mean "regular" noise or 50/60 Hz hum?

Regards,

Gunnar

I know the connector. It was used by several quasi-pro audio companies, but not in large numbers. I never liked it, for no particular reason. I've probably thrown-away dozens.

It may have been from the Cinch company, but they don't list it now. (Somehow the word "Cinch plug" now means "RCA IF/phono connector", nothing to do with the Cinch company, in operation since 1917, recently acquired by BelFuse. www.cinch.com/ Don't miss the video http://www.cinch.com/chiphead )

Or is it an old Jones connector? Cinch got some of Jones' products, but I don't see this one.

It may have been used on very early H-P gear, but then H-P moved to a connector which eventually became what we now call "IEC".

I don't like molesting nice gear, but the power entry is the place to be up-to-date with recent safety standards.

I agree 100%. Thanks for your reply.

I don't know what diameter is your original connector, but maybe a Neutrik NAC3MPA-1 could fit?
If it's the case you wouldn't need to molest the case...

Axel

Yes, that might be a good idea, thanks!

This kind of looks like a Cinch P202AB and the mate would be a S202CCT

If this might work, let me know the diameter of the hole.
I might have something in stock.

Thanks, I´ll check the diameter tomorrow when I am in the studio.

I mean regular noise, and by a little I mean very little, but If you are used to the improvements you can get by recapping/restoring a guitar amp it can be unnerving. 

It's been a while, what I remember is:
Raising the bias didn't do much.
Shielding the wiring to the front panel controls helped a bit. 
I shielded the case under the amp.
I put in a separate AC  on/off switch rather than having the AC switch stacked on the back of the volume pot. 
This was pretty useful
you'll see a few parts on the schematic that are variable, by the tremolo section.  I tried a bunch of different stuff there, I definately found a sweet spot with those parts, try using a trimpot if you can, at least while you are adjusting... 
I tried all metal film resistors, I put some of the carbons back in, I tried different types of capacitors.
I only found a few other amps with those tubes... whats it, a 6K11  something like that...  I think there's an ampeg that has that.  and the output tubes are also not too common either, but I got a nice matched set. EH I'm pretty sure.
Good luck with it.

Thanks!
