Does anyone know if a GZ37 can be mounted horizontally?

You asked this in 2006.

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!
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.

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

can I ask why does it have to be recumbent?

More aerodynamic !

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

That's the explanation I prefer

(So like my own experience)
