Hello Tubeholics! I have more than 500 RCA 5763 nos left and would try to build an OTL with them . A good idea ? 4 of them seems to equal an EL519 ? huh ? in fact i would parallel 12 of them on each pos and neg rail PSU . I dunno what to do with them ! Did somebody try a test a 6BQ5 / EL84 sub ? thank you !
Cheers
