I guess this is going out to Bob Hill in particular. I know it's been sometime but did you ever figure out the problem with the Toby amp. I'm an aficionado on Toby , Standel and Sunn early solid state amps. Anyone out there who has one please let me know. I know quite about them although currently I do not own any. Be glad to hear from anyone about the whereabouts or issues with these. Thanks.
