Magnatone Troubadour M192-5-D

[acorkos]

Anyone know anything about these amps? or have a schematic? i actually have 2 of them here....but they are different designs. one has octal preamp tubes with 6L6G power tubes, while the other has 9-pin preamp tubes with 6Y6 (?) power tubes (anyone know anything about 6Y6's?)

thanks for your help
