[Amps] MLA-2500

[Ken]

Ok guys need some help.

I went to an estate sale today and bought a MLA-2500 amp. I swear the amp
has never been used. The previous owner has passed and he was a wealthy man,
no children ect.
The amp has never had a power plug installed, the various connectors on the
rear show no sign of use, no scratches on ALC, relay or coax connectors.
Relays show no sign of ever being energized. 

Got it for a steal..I hope.

The problem..

The ready light never comes on. When I tried to tune the amp, no relays
actuate. Reading the very slim operating instructions 
I see you need to install the delay relay and the control relay, they are
installed and "look" ok.
Plate voltage is as specified in the manual. I have hooked up the relay
cable from radio to amp, no ALC yet.
Unit is wired for 220 and I ran a new dedicated 220 line. Yes, I have 220 at
the plug. 

I'm thinking it may be the delay relay. Some of you already know it's a
6no75t vacuum type.

Any suggestions before I tear into serious trouble shooting?
