Hello,

I have recently moved house and am trying to clear out alot of stuff I don't need or are unlikely to use. These are NOS mullards. Military versions I believe and there in the boxes. They have not been used. I originally got 4 of them to make a full wave rectifier after seeing a schematic for an Audionote Ongaku amp! :). I heard rave reviews about it and I was still a novice with electronics. The OPT is the key part plus the caps and construction. (how naive I was at the time!).

So yeah they could be used for SE Triode amps 211, 845 etc with large HT rails.

Anyway here is a link I come across yesterday.

http://www.mullardtubes.com/MullardRectifierTubes.aspx

To quote from the above website - "Without a doubt the finest GZ-37 available today only exceeded by the High Wycombe CV378 "Fat Glass"

I took these pictures about an hour ago.

and the price is??

Having a good look around I am looking for £180 for the four ie. $265.00. This is pretty cheap if you look at some other sites.

http://www.mullardtubes.com/Mullard-GZ-37-GZ37-CV378/?ID=0&ProductID=150

nearly $150 a tube or this one

https://www.tubeworld.com/gz37.htm

Between $100-$150 per tube. That site has some good information on it regarding the valve. I don't know enough about getters etc.

Lastly I forgot to mention that all four tubes have the same date codes YE. Mid 60's I think. As you can see from that link just above, the internal construction has changed over time. So it's a mix and match affair.

PS. Ignore delivery costs. I have stuff (palettes) going to virginia at work all the time and it will be well packed.

Best Regards

Kevin

Just thought that I should follow up on this. I spoke with Kevin and we worked out a deal on the GZ37 rectifiers.

I received them last week and everything is looking great. I'm pretty excited to use these in my 300b project.

Thanks much Kevin!

Hey Kevin,


I have been somewhat sidetracked by a couple a speaker projects I was working on and the 300B project was put on hold. I have most everything I need now however and should be back at it soon.

The 2A3 amps I bought to keep me occupied in the interim have been my downfall. They reduced the urgency to get them done quite a bit :D

I will keep you posted when they get full attention again.
