I have invested in a Beck RM-1 tube tester. Although only the ears can be the final test of a tube's musicality, it should help avoid bad tubes, at least.
What are used tubes worth ?
My ARC VT100 blew one output tube (the filament opened) so I replaced the entire octet.
So, I have seven 6550 output tubes that work fine, and have probably 800 to 1000 hours on them. They are the original tubes that came with the amp.
Any idea what they might be worth ?
Thanks.
