Hi !

For a very long time i have been thinking of building my own version of the Sussex, using parts that i have at hand - for years. The worst part is in this project as always - the main transformer. On all other than the heater voltages i have transformers for the job. But, maybe a stupid question, why not use DC for supplying the heater voltage? Supplying DC would be a very easy way out, at least in the range 2-24V at a couple of amps at the most. I think i have browsed all messages over a couple of years in this thread and found nothing - i still may have missed them...
