NOS Western Electric 101D "tennis ball" tube

I own the Coincident Statement 101D Line Stage and am using it with a matched pair of Psvane 101D-L Western Electric replica tubes.

I am curious whether anyone on this Forum has used NOS Western Electric 101D tubes in the Coincident Line Stage and, if so, how did these tubes compare to either the stock tubes or the Psvane replica tubes?

I am also interested to know the current market price of a matched pair of these NOS Western Electric tubes. Thank you for any feedback.

You're welcome! The print edition of Antique Radio Classified seems to be getting published very infrequently in the last couple of years, so what I'd suggest is a web-only subscription. You would then be able to place free want ads that would appear in an email ARC sends to all subscribers theoretically every week, but sometimes not quite that often, which contains all recently submitted classified ads.

Good luck. Regards,

Al,

I am now reading some of the archived content on Antique Radio Classified. It looks like a very useful resource. Thanks again for pointing me in this direction.

Tmmvinyl,
Be sure to check the type of pins on these 101Ds. Some are 300b type (2 thick and 2 fhin pins). Other versions have 4 pins of equal thickness. I believe adapter plates are available.

Good point, Charles. According to datasheets I have for the original WE tubes (in the book "Western Electric Tube Data" published by Antique Electronic Supply), both the tennis ball and dome versions of the vintage WE tube had 4 pins of equal thickness. Does that correspond to the configuration of the sockets on the CSLS?

Best regards,

Charles and Al,

The 101D tube sockets used in the Coincident Line Stage do indeed require two pins that are thicker than the other two. So it appears the WE 101D may not be suitable replacement for the Coincident Line Stage without first making a modification to the tube sockets.

The question now becomes whether any Audiogon member has made this modification just to try these tubes.

Thank you for your continued contributions to this thread.
