the missing link in the chain
in structural projects, there are two safety factors, static is third of dynamic.
in short I am arguing that the TUBES output transformers are undersized 3 times.
I tried to shunt the secondary in parallel instead series (4 and 8 Ohm to 2 Ohm)
...improves but not enough.
advantage of the buffer is to isolate the reactive power back from the speakers on the negative feedback of tube.
you do not have large heat sinks may adopt a bias AB1 (0.5 A)
in this case it is better to use identical components with gain (gain means speed)
I found the same gain (Hfe 100) with A1302 and C5200
two generations who marry perfectly
