[ARC5] Powering an ARC-5 Receiver After Long Storage

I have a couple of ARC-5 receivers that have been in storage for unknown
years.

In the past, I've powered radios in stages:

First, applying filament only for several hours.

Second, applying B+ only, in slow steps of about 20 V up to rated B+.

Third, applkying both Fil and B+ and checking operation.

In the second stage, there is no current through the tubes. Does anyone
have the nominal B+ current for the radios in the B+ ONLY states? This is
basically a bypass cap leakage test.

Thanks,

-John
