[TenTec] Hercules 444 amp

[Bob McGraw - K4TAX]

The last pair of 3-500's I purchased from R F Parts were of Russian origin 
as I recall.   I purchased their Matched Pair brand because of their 2 year 
warranty as opposed to the other brand which had a 1 year warranty.

So I suppose one pays their money and takes their choice or chance as one 
may have it.
