Well got my tranies from Edcor in and got her built and it's alive! Really does sound fantastic! She's a very heavy girl - more than I thought she'd be .. that's some heavy duty iron (35lbs in Edcor iron). I build them fast as I get caught up in doing this and don't even take a break or eat .. it's an illness - have to learn to go slowly and walk away. Love the 300B sound- it's my 3rd 300B ive'd owned and its tops - Thanks for all you do for our community! it's an excellent design! I did not do the copper ckct board on bottom of power trans - do have a small rubber spacer that lifts it up maybe 2-3 millimeters - everything worked out of the gate - needed no trouble shooting - voltages spot on - dead silent-no hum, Just an excellent amp!!! will probably be adding the amp meter also.
