Quit your whining!
My McIntosh mx110z Tube Tuner/Preamp has 17 tubes.
The Fisher Console I inherited from my Uncle Johnny was all tubes: Control Center; AM Tuner; FM Tuner; Stereo Tape Deck; Garrard TT; Pair of Mono Amps, then Fisher sent a crew to his NYC Apt to add a tube multiplexer for FM Stereo, Tube Phono RIAA and new Stereo Cartridge.
I put the tubes for each component in a separate paper bag just before Thanksgiving each year and headed to the Electronics Store, big console with many hinged flaps/charts with tube listings/settings. God help the people in the line behind me. My back and legs were killing me when done. Perhaps needed 2, max 3 tubes.
Get thee a Tube Tester. Nothing fancy, just the basics will give you basic answers. Find the rare short or weak tube, test new ’matched’ ones when you receive them, know the problem is elsewhere.
After complaining each year, my wife got me a small portable Accurate 157 on my birthday. Last week would have been her 79th birthday, but she died age 39. You would have liked her. Like Donna, she encouraged my efforts.
I had a big Jackson, this little one always agreed with the big one, I gave it to one of my friends.
I check all my tubes every 6 months
My horn tweeters reveal any problem, my tubes are noise free. Some friends put up with a little noise, not me.
