Post by Max N » Tue Feb 26, 2019 9:46 pm

Does anyone know if a GZ37 can be mounted horizontally?

You asked this in 2006. :lol: :lol:

I can't find any other references to horizontal mounting.

Its indirectly heated so I don't see why not. And as Andrew pointed out before, Boarder Patrol do it.

Thanks Phil, your memory is clearly much better than mine! :oops:
Thanks Nick. Reading that link reminds me that the reason I asked the question back then was because I was cloning a BP PSU for my WAD 300 PSEs.

Not my memory Max, just used Google. :)

Had you considered using a pair of damper diodes instead of the GZ37 ?

6D22s are the ones I use. About 30 secs warm up, bit more than the GZ.

Yes, I’ve used 6au4s in the past. But I have a few gz37 so I wanted to put one of them to work :)

I’d use gz37 too. Horizontally if needs be.
I can do it right or I can do it now, but I can't do it right now.

Hi Paul :)
GZ37 it is then!
I'll start a new thread when I've got some progress to show.

It has to go inside an existing enclosure - and GZ37s are surprisingly tall....

Or to put it another way, I didn't measure to check it fitted until now....

I'm with Paul on this one.. the gz37 is a good valve.. I have a pye Mozart stereo somewhere the gz34 and el34s are all horizontal its had some stick at my lads and still is fine
The tube manual is quite like a telephone book. The number of it perfect. It is useful to make it possible to speak with a girl. But we can't see her beautiful face from the telephone number
