I have some odd pentodes that are going cheap.

I know you guys are not averse to assisting ebay sellers but if anyone
can tell me what these tubes were used for I would be grateful, Yes I
have searched everywhere.

I have the 5A/152G version (which I presume is the same tube in flying
lead version)

here's the specs
