That is a common problem in the Emtron amplifier warmup timers.

Can anyone tell me how the timer works in an ETO 91b? A link to a document or 
circuit would be fine - I have neither. I have an issue with my amp where it 
occasionally fails to timeout. In fact it just takes too long anyway (sometimes 
over 15 minutes).
