Guild Thunderbass (Quantum) Schematic

Hello: I have two Quantum heads: one seems to be nearly stock and the other, let's just say, hasn't had gentle hands inside her during her life. My plan: to bring both back to their original state. My question for the Guild people: is there a schematic floating around for the Quantum specifically?-I've only had luck finding the other models. Any help at all would do me well at this point. My thanks.

Hi Hennebeau,
The schematic for the Quantum is here. Voltages run about 530 volts on the plates and it needs 8417 tubes.
Welcome to the forum!

Thank you for this! So wonderful to have this forum for reference.
