Hello to the group,
Am working with my TR 5.
Initially used a R.S. fan but was way to noisy.
Read the archives. Evan K9SQG said he used 220 V. ...soo
A Boxer 230 V. with ball bearings Pewee starts and runs fine.
Still to noisy. Made neoprene washers for the metal to metal mount...no
help.
I
a dual set in a frame I made
sitting on top of my L4B and the L4PS. Works great.

Carl,
I just installed a 24v EBM-Pabst fan on the back of my TR7. Getting 12v out of
the radio to run at about half speed. I then put a 2w 80 ohm resistor in
series to slow the fan down more yet. This is the third try
On the TR7 I use a 12V fan slowed down to about 9V with 4 series silicon
diodes. Does a great job and no noise.
