No it won’t, but to go beyond a single tube is a pain in the proverbial in terms of circuit design, and the power consumption rockets. As I’ve got older and poorer I’ve had to become more pragmatic. OK...so OTLs are undoubtedly stunning sounding pieces of kit, but the running costs in terms of the sheer amount of energy wasted on heat and the cost of replacement valves, outweigh the sonic benefits. For someone like me, on a very modest pension, OTLs are a luxury too far. They cost too much to run.
The OTL uses 100W for valve heaters and another 170W of anode dissipation in total, for output valves, input valves and rectifiers. That’s 270W idling power out of the wall to produce 1W of audio power. That’s appalling efficiency by any stretch of the imagination. A ‘normal’ push-pull, class A/B valve amp might pull 80W, which is reasonable and affordable, though not as efficient as a transistor amp, as, obviously, there are no valve heaters in those
I’ve no intention of dismantling the OTL. But for everyday use, the A60 clone is more than adequate.
