There are two versions of the gec's ,...a straight base,& a curved base..the curved base runs about $100.00 more,and many respected head-fiers,seems to think the difference in price is NOT justified...so,I went with the straight base.
I did a quick search on e-bay at those CBS tubes,..there a few different models
Which ones exactly ,should I be looking at?
Price seems very attractive
Do you have a link??
