Can anybody provide me with transistor voltages for BA284 B and C (EQ amplifiers).
I have the voltages for the boost, pre, and output amp that I obtained from the EZ1290 build guide (see below) but was hoping somebody has or could provide me with similar values for the EQ amps.

Thank You in advance for your help

Too complicated to get at least some ballpark values by recreating the (amplifying) circuits in ltspice or something?

Almost ready to start testing scratch built DIY unit so just wanted some values to test against- im certain i recreated the circuit faithfully so not terribly worried and besides they should both be close to the same. Was only asking because I thought someone might have those values since the BA283 transistor values were published for the EZ.
