For Sale: Assorted Valves

I’ve been having a bit of tidy and have some valves gathering dust so thought I’d see if they’re of use to anyone

Valves still available:

Brimar 5U4G (approx 200 hours) £15

Reflektor 6H9C/6Sl7 (less than 50 hours) £5

2 x Trigon 6SN7GT’s (approx 200 hours) £5 each

Sylvania 6SL7GT (less than 50 hours used) £10

2 x Sylvania 6SN7GTB’s - both SOLD

2 x Philips JAN6922’s - both SOLD

Mullard EZ81 (less than 50 hours used) £10

I bought all the valves as NOS but I can only give a best guess on the hours used I’m afraid.

If you need any more detailed photos let me know.

It says Sylvania VT-229 on the base. Assuming it hasn’t been re-based I’d guess that’s what’s inside the glass envelope. VT-229 is the military coding (Valve Transmitting) for a 6SL7GT

Looking at your three Trigon boxes I see two are labelled 6SN7GT and one 6SL7GT. The latter box has a 6SN7GT alongside it, suggesting a mix-up at some point. I’d venture that the Sylvania valve belongs in the 6SL7GT box.

I can see the shadow on the table-top of some lettering on this. A closer look at the lettering might reveal something about the manufacturer.

Any idea what the hours are on the 6922s?

Actually, on all of them. People will ask.

Actually that makes sense Chris as it’s a 6SL7 I use in my amp.

I’ve never actually used the valve, I bought it as a spare, so never noticed there wasn’t any branding on it. :roll_eyes:

Yep, second logo in

Date code is Nov '79 I think.

Every day is a learning day on here - thanks Graeme.

So it’s a Reflector 6H9C / 6SL7 - I’ll update the info :+1:

Usually spelt Reflektor, although since it’s a transcription from the Cyrillic I guess it’s ambiguous.


I like the reflektor valves, the 70’s being the best ones.

As you’ll have gathered I don’t know a lot about valves :grinning:

Trigon these days is a brand name owned by Edicron. They sell the Reflektor valves branded/printed with Trigon on them… Nothing wrong with that, they’re good valves. £10 each used might be a bit much for those particular items. When I have them they’re typically £7.50 rrp

Ok thanks Guy I’ll amend the listening.

The OTK mark on the base of one of them confirms they’re definitely Russian.
