Thank you Zen-Mod,
Tension seemed to me something a little'm going, and measure a capacitor morning. I hope that the amplifier until the end of the week I finished.

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
Grüße Dirk

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 ......

Transistorgehäuse 60°C
L Halter neben Transistor 49°C
Kühlkörper 39°C
verwende Wärmeleitfolie.

Amplifiers are now only 0.45 hrs. In operation. The above mentioned values after 3.5 hours. Music fortuitous.
Verstärker sind jetzt erst 0,45 Std. in Betrieb. Die oben genanten Werte nach 3,5 Std. Musik höhrens.

Hi Dirk1
Could ask where i can buy this circular shape heat sinks ?
Any source link ?
Looks good congratulations for diy such sit amplifier.
Best regards

setzen silica scheiben und warmeleit paste fur transistor
nur warmeleit paste zwischen L profile and kuehler
Hello,
Heatsink link:

@ Zen Mot.
did you mica sheets and thermal grease on the transistor?
I sometimes two 6 dB fan placed under the housing after two hours still 65 ° C.

@ Zen-Mot.
meintest du Glimmerscheiben und Wärmeleitpaste am Transistor?
Ich mal two 6 dB Lüfter unter das Gehäuse gelegt nach zwei Stunden immer noch 65 ° C.

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

Hello,
I have a question again.
Voltage before the throttle 22,95V, behind the throttle 20,97V.
Bias -4,90V but only 1,826A idle current.
Temp. 40C after 1.5 hours.
How many amps should I set as Bais?
