Got an old Bogen power amp PA for 20.00 bucks a few weeks back . A quad of 6l6 sylvanias and 2 tung sol 5u4 rect . It's using a transformer for the PI . The badge reads
David Bogen Co Inc
Bogen Sound Systems
Model No. B4 101
Serial No. 4764
115 volts 50/60 cycles
Any one fluent with the Bogen stuff ?
Can't find any info at all on it . Can it be dated by the serial number ?
I posted a few pics on another forum over at PPwatt.com if a visual will help .
