I've temporarily retired my balanced, bespoke, valve buffer / pre-amp and it's wrapped up for use in another system for another day, so I thought I'd sell off my 6SL7 valves (or their equivalents). All are in perfect working order, and all are matched pairs except the single Melz.

So, if you're after some 6SL7s to try or what is pretty much considered to be the best, then look no further! Price includes postage within the UK. I'm not sending these overseas, it's just way too much hassle these days. Payment by bank transfer or PayPal Friends / Family, whichever suits you.

If anyone would like some info on the buffer/pre-amp then please do PM. I didn't intend to sell it but if you want to know about it then let me know.

Weighty, crisp and immediate in their presentation. I love these valves! These are the military spec ones and are impossibly well made, even though they look a bit "Russian". :)

Simply stunning audio, massive and clean presentation, incredible bass! My favourites, I used these almost exclusively in my system. These are getting very hard to find now. Rated for 10,000+ hours, these will easily go on for longer than that.

Quite useful in some systems, not so much in others. Your mileage will vary. Cheap enough to try out for a laugh!

Are the Melz the "5 hole version"?

[Filterlab]

Not sure to be honest. What's the tell?

[Wakefield Turntables]

Have a look at this, it's not the valve (very close) but you will see 5 weld spots in the metal base.
