Thank you for your kind comments. Truth is, I am perfectly happy to listen to the offspring of a 6SN7 and a 6DJ8. This baby is called 8FQ7 and made for Raytheon in Japan, probably by Hitachi. This tube has amazing clarity and musicality, and great treble and amazing bass detail and punch.
But I am not adverse to try 6SN7 as power tubes; I am just wondering if I am capable of building the adapters needed. Gibosi's solderless breadboard solution suits me fine,
Actually, mordy, I'm beginning to feel that rather than castigate you (and mab) I should be sending you (and him) my greatest thanks...I'm sensing in my bones that good things are on their way (literally!). So now, rather than with trepidation, I am awaiting the consequences of my rash decision with eagerness.
At the very least perhaps I may have helped gee things along a bit in this particular direction (but full marks go to mab, of course)...and to echo gibosi's sentiments, it amazes me also what we are able to do with our LDs...and still they beg for more! I can't think of any other units that are so forgiving, or that have made such massive improvements from stock without the need for equally massive (and costly) mods...perhaps somebody else knows differently?...
