38-116 code 125 volume issues
#1

I am looking at a 38-116 for someone and it has been fully recapped and out of tolerance resistors replaced ( not by me but well done, nothing sloppy). 

Complaint is ,the volume is low and sounds like a crappy transistor radio. This thing should boom. 

I checked the bias voltage at the 6l6 tubes ( pin 5) and they have -25v on them so that is not the issue. 

Plate voltages seem a bit high, I attribute that to DMM. ( about 44 volts high on 6l6 plates and screen) . 

It also seems like there is lack of tone. every thing is tinny sounding.  output xformer check, field coil checked. 

speaker subbed to rule out speaker , still sounds like crap. 

Supposedly new tubes were put in. 

I don't know if an alignment was done.

point my in a direction of what to check next.
