Re: OTLs, QUAD 988 and ZEROs

You wrote, "My OTLs were made custom for my Quads so there is no problem about compatibility between the devices". Obviously not, since you are using the combination and are evidently very satisfied. But your response still does not give us any useful information about your amplifiers. Possibly you can consult the person who made them for you. If they utilize a lot of negative feedback (NFB) to achieve a low output impedance, then most likely you will not get much benefit from the Zeros. What type of output tube do your amps use? How many output tubes per channel? Do you know whether the output stage is a circlotron type or a Futterman type?
