November 15, 200619 yr Author What are the tubes and what is the circuit topology?I still need to get more info on that. I think the 4 6GU7's are the input tubes and the 4 6H30's are the output tubes, with the 4 27GB5 Pentodes used in the CCS' and the other Pentode [forget which he used] as a regulator, but I am not 100% on that. I also know that there is no feedback being used and that he employs negative PSU's for some or all of the stages. There are 8 power supplies in total I believe.

November 23, 200619 yr Aerius please pay attention. That tube is completely and utterly useless for otl audio applications. Look at the Rp. Look at the fact that the sweet spot is 2500 volts and about 500ma. Decent output caps for that thing would be about the size of a gallon of milk. EACH.
November 23, 200619 yr Whoops, forgot the OTL part. I was thinking transformer output since that has been done, but even then the transformers weighed 40 pounds or something ridiculous like that.
