Rectifier For Cary SLP 05

Is Dan Wemmer still at Cary?
No reply as yet and it is way after the weekend.

@testpilot here's hoping it does last forever.
@rodman99999 how do the Phillips GZ34's sound vis-a-vis the Mullard?
@tvad I am checking with Cary on both the Brimar and the Mullard GZ37 nut as it is the weekend I thought I may get a quicker response here from folk who may have tried one.

Just an update so other folk will know for the future. Cary says it is electrically the same but will not fit because of the size.
Also, they don't recommend a directly heated rectifier 5R4 or 5U4 on the SLP-05. " Use indirectly heated tubes like the 5AR4, 5V4/GZ34, CV1377, GZ32, GZ33, CV729."
In any case, the reply came too late as the seller couldn't wait and sold the Brimar. Not that it mattered in the end.
