There are 2 reasons to be VERY cautious about the substitution: forward drop in the GZ32/5V4 is less than that in the GZ30/5Z4 and 1st filter cap. size limits. Do you want to over voltage your signal tubes and/or have a 5V4 arc over at power turn on?Do a little digging and you'll see that the characteristics of the 5Z4 and 5Y3 are quite close. The 6087/5Y3WGTB has a cathode sleeve, like the 5Z4. ;>)
edit: corrected 5687 "fat finger" error/6087 is correct

Thanks Eli!

Eli,
I believe you meant 6087. GE made some fine mil spec 6087's. A nice slow-start "5Y3WGT" rectifier. I also like the Bendix 6106 in some 5Y3GT applications. The 6106 has a really slow-start character (like 15-30 seconds).
"I believe you meant 6087."
Correct! My fingers were fat. :> ( I'll try to edit the error. Yes, the GEs are nice. Raytheon made some excellent 6087s too.
The 6106 is fabulous, but can be very pricey. Talk about a TOUGH hombre, the 6106 was used in Nike SAMs. The type sounds damned good too.

The 6106 wasn't used in the Nike missile itself, but it was used in the radar, radio and LCT equipment. I have a couple and they are rugged!
