So yesterday I got a bit impulsive, I threw an amp design together in about 4 hours and then ordered a heap load of parts. I may not have spent a massive amount of time drawing the schematic but I've been wanting to do something like this for a while. Bimodal comes from statistics (least favourite area of maths) and is a special type of distribution with 2 peaks. Single ECC83/12AX7 preamp: Hi and Lo inputs (on a switch to save space inside the chassis rather than 2 jacks). Hi setting is both triodes cascaded. Lo is a singular triode gain stage. Switchable tone stack: Deluxe Reverb (Black) AD15 (Orange) ECC83/12AX7 Paraphase inverter - Need high gain for the Lo setting. ECC82/12AU7 Push-Pull Power amp - micro amp 1 Watt. Input is V1 on the far centre left and the PT voltage is V2 in the lower right corner (rectifier diodes are missing). To save space I'm mounting all the large 450V filter caps onto an octal valve base to make some sort of Cap can. I still need to buy an enclosure but I'm going to wait for the parts to arrive so I can take measurements and decide on the best layout. I have a crap track record for all of the following starting projects, finishing them and documenting them but I'm going to do my best to document this build start to finish on this thread.
