I don't think anything really bad would happen- it's possible that HT would be a few volts low compared to a good UY42, resulting in the set running a little cooler! If the UCH81 was really tired, the LO might stop on some bands or sections of bands but it would have to be well knackered and on its way out anyway to be affected by a small percentage HT drop. If you were really pedantic, you might be able to measure a slight drop in maximum audio output capability but in subjective aural terms it would be unlikely to bother you,
