Mark, Make sure you use plenty of heat sink compound on the HOT also. It will definitely make a difference. Joe

Those output transistors on the 187 do tend to run hot from my experience. Leave it on and play it for a few days before returning it to the customer just to make sure. So long as the heatsink doesn't "sizzle" spit on the

of your finger then the temperature of the heatsink is probably OK.

Hello Techs, Working on a RCA Ctc187CL3 which came in dead.FBT was bad Changed it and the HOT after checking all the electrolytics in the horizontal section along with the diodes,the driver transistor and transformer and some resistors.Set came on and worked well for about 10 minutes then HOT went again.I had used a cheaper generic so I stopped looking at the pennies and replaced it with a genuine RCA replacement(#223942)This time I let it run for about five minutes,turned it off and checked the HOT it had gotten so hot that even though I could touch it I could not leave my finger on it.Is there anything that I am overlooking here?Need some help with this one.T.I.A.
