Hey guys… but too exhausted to fully comment tonight but will count back in am. Input transformers are for sonic improvement. A few examples of the agartha are out there with custom input transformers that provide step up. With all these super hot dscs it became less desired. The pre does a...- ampsandsound

El37s are pin compatible but it's almost like a 6L6GB but as a pentode. Its Max plate is 400v for which the Bigger Ben/Mogwai SE and Nautilus exceeds. Use at your own risk! It's very similar to 807s with an adapter. Mil Spec 807s handle the voltage without issue... but not all NOS 807s are...- ampsandsound

It’s not just a question of voltage but of the drive func. More voltage lends to more better dynamic range but not whole story. Gain/drive is where dynamics live. Too much gain and you have noise. Not enough and there is not life. Pre amps should give gain…. That all said every system is...- ampsandsound

Sorry for a late chime in but on I’m vacation currently. We don’t go into breakdown of how we load the output stage… That said, there’s lots of variables to be considered, pri impedance vs (selected output) sec impedance, tube choice and impedance of VC which is not constant. The Forge is...- ampsandsound

A 12Bh7 will likely increase current and not gain. 12AX7 with give you most gain. If wanting to ekk out most power... 12AX7 and then some pre on the front would be the path forwards. The 12BH7 is fantastic choice but not for power.- ampsandsound

Erik, I can appreciate your frustration with my prices. You may not understand the actual time spent building a Red October. They are extraordinarily time intensive. Regarding use of zip ties, we dont create a wire harness as you could not optimize/ have the shortest wire runs. The zip ties...- ampsandsound
