Default Re: What did I get myself into? Murphy A40C.

Lots of work done on this past few days. Cabinet is finished and drying. Rails painted, grill mesh cleaned a number of times and varnished too. I'll probably assemble the cabinet innards today, also done initial chassis check and cleanup now(that was not fun!) and I think I've got 3 dead valves.
The MU14 in the transformer board is definitely dead, does not light up and I can see a bit of glass in the valve so something in there cracked/exploded
I can hear something inside one of the AC4/PEN and AC/VP2 valves.
Is there any way to test these without a dedicated valve tester?
Powered it on the freshly made bulb limiter for a minute or two. Everything lights up so I guess transformer is fine. Green eye does not come up.
I'll get the replacement valves and start recapping it.
