I was mighty glad to see that this model of Tx with a separate receiver still exists.
Indeed from my side I still possess this beautiful line.
On the otherhand, I have changed the microphone namely, I am using the "PEIKER" TM-121 wich works better than the usual microphone from yaesu.
The "PEIKer" works in the highest frequencies I mean more to the 20kHz than 20 Hz.
I have purchased some spareparts (tubes 6JS6C) and 12BY7A.
I know that some radio-ham's change the tubes into 6146B.
At present I only work on 20 mtr band with a simple homebrew "dipole"
i wish you my kind regards
