Edrel made a better design for the 6bm8 who owns audio nirvana. Yes, pina custom made ko circuit particularly for audio nirvana super 8. Our reference set tube is el84 but i think a little bit better SQ because of the upgraded design and trannies. Power supply are all oil caps. Signal cap are also oil caps. 25k price. Pero kung sasabay kayo sa akin 20k. Kasi yung housing tlgang papagandahin. Vol.pot is alps. Wooden sidings. 2 inputs. Mga 10kilos more or less ang bigat. Speaker terminal are 5 way binding post yung clear. Yung mga oil caps power supply sinlaki ng lata ligo sardines. In addition to this naka "choke" siya for better sq talaga.
Pls.PM edrel if interested para maka mura tayo 20k n lang. Mura dahil makakatipid sa gagawa ng housing/casing pag madami. 100% maayos ang gawa.
6bm8 Super Triode History

http://www.audioasylum.com/cgi/t.mpl?f=tubes&m=132198As per my personal experience with proto type 6BM8 SET using electrolytic caps and not oil caps, the SQ is very good. Low deep bass, Depth and Soundstage...very good. I won't invest on something that will not work perfectly with my Audio Nirvana. So, this is only the basic 6BM8. The one in the making, my own 6BM8 is a different story.
