Hi,
Please note this is not a for sale ad, though in time I will freely admit it might get to that. If I overstep please let me know, right now I need info and ideas.
So I opened another box yesterday, I've been going through a few from a large buy of various AF and RF parts some years back that I have done little with. Recently I have found a few boxes full of tube sleeves with a mix of different double triodes, pentodes and some oddballs, all regular small B7, B9 and octal stuff. Today was different. As I found with some others all the tubes in this box were wrapped in paper, one in a heavy waxed paper with padding but all the others in regular heavy brown paper. In total the box contained 7 similar tubes
1 x United 211W
1 x GE 845
1 x RCA 845
1 x United 845W of specific batch and date code
3 x United 845W of same batch and date code
3 x 4 pin jumbo bases to suit
Hmm!
The GE and single United 845 have brown deposit to the glass but all other look unused. Bases have had heater connections soldered before but not grid or plate.
I have tested all for filament and had them light up good.
Next step I need to understand what I need to do to characterize this bunch?
I don't have an 845 amp, nor do I see building one, but I would like to know that they are, or are not any good.
At that point I might have to seriously consider how I might dispose of such a clutch.
In addition to these in the same box were a pair of 5-500 tubes and I also have boxes with what look like a pair of good 4-1000A tubes. Should I be looking for transformers or building table lamps?
Thanks for any help and ideas.
