Hi Guys
A couple of very rare pairs that that don't come up often:
2 x 6SL7 GT FIVRE ROUND PLATES and getters.
These are wonderful tubes manufactured in Italy and the round plate type is particularly highly regarded- the one to look out for. £135
2 x BRIMAR 6SL7 GTY matching date codes 1A6 (1956 manufacture).
Top of the pyramid 6SL7s. Uber-rare, with increasingly eye-watering eBay prices. Sound? I find them very similar to the excellent TungSol 6U7 GTY.
