Truetone D-726
#1

I have a Truetone D 726 but the better print is from Allied A9775 (Riders 8-5) link here apparently it was made by Continental , Admiral? Allied anyway.
http://www.nostalgiaair.org/pagesbymode ... 000752.pdf

I have tested the tubes and they are good.
Field coil measures good at just over 1100 ohms
Output xformer was open and replaced with a new one PT-291(Antique Electric supply) I can use a 9v battery and can get sound through the speaker and output xformer.
6.3v on the filaments
80 tube pins 3-2 380vac, 3-gr-212ac, 2-gr 174ac. pins 1&4 5v Power transformer good.
I have replaced the filter caps
I have not fully recapped as I wanted to power it up and at least hear static but I get nothing dead air.

One question I have concerns the filter caps. On the print it shows 150v off the 4mf (I only get 88v Very low) but only get 7v off the 8mf ( nothing on the print, can this be correct?
What am I missing?
Eric.
