[QUOTE="Emperor-TK, post: 147452, member: 3531"] I'm currently building a two module bass amp for Egnater/MTS modules, so I've recently been popping in here lately (just joined today). Your pin-out looks right to me, I'd just like to add: pins 3,4,5,6,E,F are the module's signal ground plane pins M,N are the modules heater ground for the module's 12V Vreg pin A is HT ground pin 10 is filtered but unregulated DC heater voltage which gets regulated to 12V in the module The B+ is 300V nominal but the zener diode pass-transistor regulation in the Egnaters/Randals is a little loose. It varies from 300 to 320 depending on load. I'm using a TL783 Vreg in mine for a rock solid 300V. [/QUOTE]
