[Amps] henry 2-kd classic desktop amp

[Douglas Johnson via Amps]

Hi, looking for some ideas on the henry amp I bought at an estate sale. It was wired 110v and when plugged in did nothing, no start or anything. Converted it to 220v ac and it immediately came to life, appeared everthing was working until the power out was checked. Very low output on all bands ( 200-300w) plate voltage is somewhat low ( 2600, ssb ) I suspect one of the p.s. caps is dead, but plate current is 600mils and grid current is 200mils , both in spec to the manual. idle current is 80 mils, cutoff is ok. Checked the input swr on all bands and saw no problems there.  I had a brand new set of tubes on hand and after installing them had the same results on all bands. any ideas?...Doug,w9iix
