Re: octal preamp
Mr. UR12, great clips! What power section set up is that? What is the trans voltage and OT? My single ended Rocket preamp-Adams SE power section is on hold due to a dead OT somehow. Until I get a new one I might want to build an octal after all! Thanks, Andrew

Are there any more ROCKET layout out there with just two EL84s? The only one I can find is the A0 version that has four. Thanks, Andrew
