Salas hotrodded blue DCB1 build

Can I just check, I have a new Transformer I want to use for convenience (has other useful voltages for my pre-amp remote volume and led volume resistors. It's 2x15VAC but on UK system runs to 18.3VAC.

With 18.3VAC hotrodded DCB1 running at 9.14 DC, how big should my MOSFET sinks be? Will normal small cast sinks do the job? Like these I have on at the moment:

Many thanks

Hi Salas,

Well, it's those standard Hotrod 5W 10R Dale resistors. Is that what you mean, or do you want me to take a measurement from somewhere?

I'm guessing it will be fairly hot with 18vAC transformer, right.

My last one worked great - it was 14vAC, but this new 18vAC one has some other useful secondaries for this amp, and is R-core so low EMI (It's a small box).

Thanks
Lucas
