[ARC5] Resistance BC-453, BC-454

[J Mcvey]

 Did you see my posts about the probable area to check? Look in the vicinity where the resistance is the least!All of the other reading are low due to one fault. find and remove  that fault and all the others will be ok.
It is obviously a resistive short in the plate B+ line from the numbers you showed us.

 Hi Chris,

You didn't say how you 'checked' the tubes nor how you checked the 
resistors and capacitors. You also said "more or less" about the 
resistors. They are either in spec or out. Try pulling tubes and measure 
again with the empty tube sockets.

Wandering around in the radio with a hot soldering iron and solder can 
get a small (sometimes quite large) bit of solder in a bad place. Look 
for something like that. If you don't see something obvious you will 
have isolate various parts of the radio to find the fault. It's an 
ancient technique of  "divide and conquer". Good luck to you with your 
project. When you get it all working it will be worth the effort:)
