Alamo amplifier schematics

[witchfinder general]

I am looking for a schematic for an 1967 Alamo Super Band 2578 piggy back amplifier. Or any information someone has on this model. I know it's hard to find this if at all. Please help if you can. My amp is in great shape but from what I have read it may have "leaking caps". I should have a ground installed. And new tubes at some point. Can you bias these old amplifiers? I have many questions about this amp. The amp sounds awesome. The strange distortion on certain clean notes only happened after the amp was on for quite awhile on nice and hot.
