Seems a pity to run right and left channel DHT heaters off the same supply. DC heaters won't help you with 2a3.

You must be running them in parallel... not sure about how the hum-buck pots will behave since they are also in parallel - I have a pretty good idea it will ossilate though...

How does it sound if you only run ONE channel?

Best to go for disco's advise in any case. 29 euro for a pair of DHT heater supplies is a good deal!
