I cannot answer that question.? If you don’t already have one, your best bet is to get a service

manual for the receiver.? You can get them from various sources such as radioreprints.? Do a google

search.? I do not know if you are setup with test equipment but you may want to think about getting some

of the basics if you are into restoring? these old radios.? I too get all my tubes from the same company and

I have found some of the tubes not up to par.? Don’t assume because they are in a box, they are good.? Unless

you tell them to test them prior to delivery, it’s pot luck.? One of the first items I got was an old tube checker

of which many are found on Ebay.? It took (3) tries to get the one I needed.? If you order any tubes from any

vendors, tell them to check them first.? It costs a little more but it is worth it.? In the meantime, go get the

manual if you don’t already have one.? Good luck with it.
