L'Amp: A simple SIT Amp

hello,
I would like to thank who have made the project possible and helped me at all.

The Amplifier are great, better than I had thought.

If the lower values of the amplifier ok.

Temperature after 3.5 hours. Measured directly on the housing of 2SK82 83 ° C.
Heat sink 50 ° C
Voltage from 21.5 to 21.8 volts
Bias -5.5 volts

Greetings Dirk



Hallo,
ich möchte mich bei allen bedanken die das Projekt möglich gemacht und mir geholfen haben.

Die Verstäker sind toll, besser als ich gedacht hatte.

Sind die unteren Werte des Verstärkers ok.

Temperatur nach 3,5 Std. direkt am Gehäuse des 2SK82 gemessen 83°C.
Kühlkörper 50°C
Spannung 21,5 - 21,8 Volt
Bias -5,5 Volt

you have 83C at transistor; way too much for my liking

give us temperature directly at L bracket near transistor and temperature at main heatsink near L bracket

do you have temp. conducting grease between transistor and L bracket , same as between L bracket and main heatsink ?

from pictures it seems there isn't temp. grease ......
 
Hello,
I have a question again.
Voltage before the throttle 23,8V, behind the throttle 21,8V.
Bias -4,98V but only 1,834A idle current.
Temp. 34C after 45 min.
As far as I can so that I turn down the Baisspannung 2A idle power come from?
Greeting Dirk
