This transceiver was destroyed… The PA was burned. Now in good health !
All transistors except Driver and PA with tubes.
YAESU TRIO TEMPO-ONE
Similar with a FT200.
I have this unit since 1980… Sleeping in a corner of my shack.
Lot of work to restore it… Bad caps, bad tuning,…
Now it is alive and nice to use.
I buy it in a Hamfest in November ‘s 2018 for just 50 euros. This poor transceiver was in very bad conditions. He was sleeping in a wet place during several years and inside is lot of dusty part…
I first clean it, change lot of resistors and caps. Realign it. Now the receiver part is OK. For the transmit part i get around 110w with new 6KD6. But i have a large problem in the mode switch because lot of bad contacts. I have now to undolder all the wires on this switch and to change it with a new one….
Some easy tools to restore it: (thanks Alain F1LAG, my brother)
