Does anyone know of a source for manual with schematic with calibration proceedure for this model. Tried all the usual. Yes, I know it's grid emission & gas and "Goodness" but it does have two internal pots, for transistor "VTVM". Thanks JAD

I don't, but someone must have it, since that model was sold as a kit too.

Thanks Allen - thats more then I knew, though from burned insulation etc, that was my guess. JAD
