What 6922's tubes are you using in your lamm s ?

Tvad, Maybe,But it makes me wonder when the OP leaves this early in their thread.
Do you still have the Blackburns ? Can I ask where did you
get them??
Man, Lamm sure makes great stuff.I would love to try his Amps.Can't afford them though.

I bought most, if not all of my Mullard Blackburn tubes from E-Bay sellers. I was fortunate to find honest sellers who delivered tubes that tested exactly as advertised.

I use Amperex Bugle Boy 6DJ8's (early 60's) in my M1.2 - I like them ;)

yes, its the M1.1s or the newer M1.2 Reference.
They use 6922s
