So I've decided to build an amp. A twin channel 18 watt amp based loosely on the 1974x Marshall from the 60s. The first channel will be more or less the same as the original 18 watt's, just a volume and tone knob and very little gain from the preamp, all the drive will come from the two EL84s in the power section. The second channel will have Gain, Treble, Mid, Bass and Master Volume. This will be a higher gain channel with more preamp drive than the normal channel. Befiore you ask, the gain knob and pot will go into the lo input on the second channel, as I won't be needing that input 😀
Instead of having a power switch like all other amps (design flaw), mine will have a switched pot that switches it on and off (duh!) as well as control the loudness of the amp by varying voltages to the power amp and phase inverter. So I'll be able to get proper power section drive at any volume.
To get things rolling, I present the first component of my amp, its also the only one I have at the moment.
