To make the HT-5R MkII sound full and toneful even at the lowest volume levels, we designed a low powered push-pull power amp which produces the crunch and break-up characteristics of a traditional 100W output stage, but at a much lower volume. This is achieved by the use of a 12BH7 dual triode valve in push-pull configuration producing 5 Watts output, which is rich in valve harmonics and compression.
