I have a 350 watt Bass AMplifier with 6 x 6550's. I have completely restored it, adjusted the bias and hum controls properly and the only thing I cannot adjust is the balance control which I assume balances the sine wave on the output evenly on either bank of 6550s. I don't have a 350W 4ohm load that would enable me to put a signal generator on the input and adjust with my scope so any ideas? I guess i could do it really quickly with the speaker cab attached but will be quite loud. Any ideas?
