[QUOTE="Timber_MG, post: 982330, member: 18"] The top end bandwidth and the resonant behaviour imparted to the output by the combination of OPT's leakage inductance/capacitance have to guarantee a stable amplifier first of all I'd think. 70Hz for a guitar cab is fine, but for HiFi use a transformer saturating at 70Hz is likely destined for application in a guitar cab. The serious OPTs out there for PP operation have saturation points quit low for full power (and result in beefy iron and as a result complex segmentation). [/QUOTE]
