[Vintage-Audio] 7591 replacements

Wed Jun 5 13:35:01 2002

I thought so. I had an ST-70, and each pair of 7591's I put in would get
microphonic after a few months. My solution was to buy a set of Radio Shack
LIFETIME 7591's, and get free replacements when they went microphonic. They
never went microphonic! Had the amp about 5 more years, and the tubes were
still just fine. I wonder how Radio Shack replaces these LIFETIME tubes
today. Of course, I wish I still had the amp.--Mike--WV2ZOW
