|Bill, a number of things. some did not light. many that did not, no electrons flowed through them. I have a tube tested and these became duds from just sitting around. The finals were new when I put it away. the glass in those tube just sort of disintegrated in various spots..mostly at the base and tops were the metal connectors are. Only about 10% were OK...if my old tube tester is correct. Some the filament no longer lit.. Rig was stored inside a heated house and it was in a sealed box and no one touched it or disturbed it. Sort of a surprise to me since I expected maybe one or two to get gassy but the finals that were brand new tubes not new old stock... went bad at the tops. I remember years ago Russia was still making tubes. I guess they are out of that business and now invading countries again.|

This is the 15 to 160 model with power supply. I had it fixed by a ham twice and now it has failed again. I am looking for someone else who is qualified to fix it. Receive and CW works but transmit audio went out again. I am guessing but a more rugged transistor should probably be installed. wonder if anyone else has had this problem of the auto transmit going out all the time. CW output is OK.

Just took out my Galaxy V from storage.... that has been in storage for about 30 yrs. It was working perfectly when I put it away and then my work took me away from home for a long time. when I opened the packaging... there of course was not physical damage or moisture or water or anything.. but about 80% of the tubes went south by just being in storage.. no none were broken . They just are dead. I am afraid I know the answer to this question.... is the any reliable source of tubes anymore??? any where??? I do not trust new old stock since that is what I had in the Galaxy before I put it away. It was re-tubed with back then with what were new tubes. I guess I have a paper weight on my hands but it does not hurt to ask.
