Hey,
I decided to start a new thread to share my building process and hopefully get some insights.
this is actually my first "complete" diy project (i.e - not a kit).
i built 2 fetboy gain modules on veroboard, i plan to create a "modular" preamp where i can change the gain modules to test different flavours. this all should be on a 500 series style board.
i just finished the 2 blocks, i connected them, wired up an OEP A262A3E transformer, and started expiremnting.
i dont plan on using an outputput transformer, but i might add a blanced line driver.
i do have some thoughts, maybe you guys and gals can shed some light on:
1. what should be the resistor value connected beetween the secondaries of the transformer? the gain block itself has input impedance of 10M..
2. i noticed the darlingtons are getting quite hot, even though only ~30mA goes through them, should i worry?
3. i plan on adding a That 1646 line driver after the second gain block, with a volume control similiar to the one between the 1st and 2nd blocks, to get a trimmer kind of behaviour. what do you think?
