Happy holidays and merry Christmas all.
I've come across a 6087 / 5Y3WGTB rectifier and have a question. Is the 6087 a direct sub for a 5Y3GT?
I'm finding some vague information and some of it is conflicting. I've read something hinting that the 6087 is equivalent to a Bendix 6106 which I don't think is a direct sub in all cases.
Please shed some light. Thanks.

Both the 6087/5Y3WGTB and the 6106 have cathode sleeves. Therefore, you take the "raw" B+ off pin 8. Some units may take 5Y3 rectified B+ off a CT on the 5 VAC winding. Those units require some tweaking. Other than that, the 1/2 indirectly heated variants drop right in.

I've seen very few circuits taking B+ from a 5V center tap. Most 5Y3 circuits take it from pin 8, and are compatible with rectifiers with cathodes. The delayed turn-on with the cathode tube is a bonus, too.
The CT is actually better, when a directly heated type is employed. The lowest residual hum is achieved. Since CTs cost money, they are not particularly commonplace..

Great. I'll have to check the circuit. Simple enough for even me to figure out.
Thanks
I've been using the 6087 and 6106 in many 5Y3GT amps. No problems. Both mil spec rectifiers are slow startup, if that is an issue.
