@PSVANE

hello,
some info please...
CV181 is not a 6SN7, similar but not the same (at least in NOS tubes), and 6SN7 is not a 6SN7GTB... quite differet voltage plate with
- 6SN7 --> voltage plate 250V (example https://frank.pocnet.net/sheets/082/6/6SN7.pdf))
- 6SN7GT --> voltage plate 300V (example https://frank.pocnet.net/sheets/137/6/6SN7GT.pdf
- 6SN7GTB --> voltage plate 450V (example https://frank.pocnet.net/sheets/093/6/6SN7GTB.pdf)

but you declare your tube matching both items, CV181 and 6SN7, so...

question 1: what is the NOMINAL voltage plate of your CV181 "horizon"?
question 2: where is possible to download a technical datasheet with all the info about the product?

using, for example, a tube rated 250V in a circuit running at 350V will cause at least a very short lifespan... if not, as conseguence, potential damages in circuit (dipend how the tube die)

a tube in a circuit is a delicate argument, ambiguity in spec declaration is something that generate a big WARNING in just a little skilled customers... more precise info would be very appreciated and a benefit for your sell too

thanks in advance
