Ok, I understand. I read more than two cases of PSVane problems, on other forums such as audio asylum.
Maybe they have / will resolve the problems of QC. Sorry if I seem to be obsessing, only I had a transformer
go out in my SET MBs with a tube failure. I think it was a structure issue. Most tubes go gently and let us know
with fussy treble as waffly bass. Plus with the BHSE you can check the off-set to see any drift periodically.
So, next question - has anyone tried the Genalex Gold Lion KT77 and seen it is solid / reliable / long life.
I read some glowing (sorry no pun) reviews on thoose tubes. It is not an EL34 so a bit brighter maybe than stock?
It might suit those 007 users?
I understand your concern about the QC of the Psvane PH tubes Julian, because that was the reason I didn't order any after first hearing about how good they were supposed to be, but AFAIK those that had problems with their PH's got them on eBay, whereas I got mine from Grant Fidelity and have had no problems with them yet, I also think others that's got theirs from Grant Fidelity have also had no problems, but I can't say for sure.
Using the 009's with the BHSE while using PH tubes IMO is a match made in heaven, but I can't say that when I heard the 007mk2's.
