Mullard GZ37/CV378
Attention! Before buying any 5AR4, 5U4, GZ33, or GZ37, here is a hot ticket from Uncle Kevvy: Buy the Philips 5R4GYS made in Holland. Click here for info. Very rare. We got a stash of them, and they are incredible. The only thing you have to do it make sure that sure you have enough height clearance... we provide you a picture illustrating the height of them so there's no surprises.
Now: On to the Mullard GZ37: In original military boxes made in the 1960's. Similar to the GZ33, but the net result with be a small drop in plate voltage to your power tubes and perhaps a slightly softer top and bottom.
