Last night I measured My lowest Hum level ...






Yes my All DHT, All AC Heated 26-26 DC coupled 45 Stereo SET amp,
A month ago my Fluke 87 meter read 0.38mvAC at left side speaker
post and right side read 0.27mvAC .

After doing a little tweaking . My leftside reads 0.23mvAC and the
right side now reads 0.16mvAC.

The hum from this amp is now barely audible, This is all thru
Altec GPA 604 woofer in a MLTL cabinets and a seperate JBLdriver and
horn , with modified Altec Passive crossover .

This is all DHT on the cheap !

Have fun
Willie
