Hi

This is VU2YK.

Last week I used my TS-450S and it was in perfect working condition.
Amazing receiver and get unsolicited comments about nice TX audio
with stock mic. The lightning fast relayless Rx/Tx switching is
noiseless and any CW Ops delight. Full 100 watts out on all HF bands.

Yesterday I switched on the rig, and shock and awe ! Output power
reduced to 20 watts ! All else remains same. Low SWR, Power supply
rock steady. ALC indicator does not move, indicating some problem
inside. I did not touch the rig in the last few days.

The important symptoms are :

1. NO ALC movement of meter
2. Power output down to 20 W on 20 M, low on other bands
3. Shack temp had become very hot last few days. Day temp in shade is 40 degrees C plus.
4.I checked all power and antenna cable connections. Receive is 100 % OK and power cable are clean. SWR is 1:1

Will appreciate any help in diagnosing and rectifying the problem. Thanks !
