Malcolm Posted December 31, 2013 Posted December 31, 2013 Still having the stacked ply cases Mal? Yes but they will be painted, I know painted .
Upfront Posted December 31, 2013 Posted December 31, 2013 If it's like the rest of your work mate, it will look magnificent.
davidsss Posted January 2, 2014 Posted January 2, 2014 Hey Tasso, what are 101D tubes used for? I have one as a rectifier in my Melody but are they also used for something else? DS
ehtcom Posted January 2, 2014 Posted January 2, 2014 Hey Tasso, what are 101D tubes used for? I have one as a rectifier in my Melody but are they also used for something else? DS The 101D is a voice frequency and carrier-frequency amplifier. In your case, it's used as a voltage regulator for the small signal tubes. I think. Cheers, Earle.
TP1 Posted January 3, 2014 Posted January 3, 2014 Hey Tasso, what are 101D tubes used for? I have one as a rectifier in my Melody but are they also used for something else? DS In the Melody they are used for rectification as Earle said. In the Coincident Statement Line Stage and a couple of other preamps they are used as a gain stage. Their original use was for telephony in the 1920's but being DHT they can provide a stunning sound. As we have seen there are many tubes being used for audio these days that had their genesis in other applications. Western Electric tightly controlled the distribution of 101D and did not permit other companies to manufacture them. Consequently they were not widely used for audio until recently when the Chinese tube manufacturers entered the market. NOS WE tubes are incredibly expensive and can fetch over $2k for a very old pair and their pin sizes do not match the new ones. PSVane obviously saw a market for an exact replica and thankfully they make 2 versions, 1 with the original pin size and another with the newer 300B pin sizes. They cost me around $680 in Guangzhou for the pair and I think they are worth every penny.

Solid state rectifiers are used because they are cheap and easy. Cheers, Earle. 3

TP1 Posted January 3, 2014 Posted January 3, 2014 (edited) solid state rectifiers may indeed be easy but have many other advantages. I think both our comments could spark a debate on the issue so if people are interested can we do it in a new thread. This one has been pretty good sticking to tubes without judgement being passed on designs Edited January 3, 2014 by Tasso
betty boop Posted January 3, 2014 Posted January 3, 2014 yes all very intersting but less side tracks and more show us your tubes hehe

STC 4101D? http://www.r-type.org/exhib/aaj0177.htm STC also manufactured quite a few other WE equivalents 4300B, 4310A, etc Edited January 3, 2014 by damohpi

But wasn't STC related in some way to Western Electric? In any event they are the exception to the general rule quoted in the article.

WhoRu? Posted January 26, 2014 Posted January 26, 2014 Can't see them but I know they're in there.... 5
Soundscape Posted January 26, 2014 Posted January 26, 2014 Amazing photos, Keitha. Some of the sexiest tube shots I have ever seen. Does that sound dirty?
Keith Anderson Posted January 26, 2014 Posted January 26, 2014 Thanks, shame about the piano black finish, impossible to keep it clean without a proper vacuum booth to suck the dust out. These are just ambient light shots and you can even see me in some of the tubes :blink:
Soundscape Posted January 26, 2014 Posted January 26, 2014 Lol, now that you mention it, I can see a pair of legs and a blurry face in there. A little dust maybe, but all that smooth glass and lovely warm glow. Very nice.
