tekguy:
Hi all,i have just built a aliexpress 150 watt electronic lm324 kit,the most it will sink is 5a with a 15v input,only 2 of the ceramic resistors going to  source of each fet gets warm so i suspect faulty fets,can anyone recomend a good sub?,cheers.

Hamelec:
do you have more details?
there are more than one electronic loads out there..

tekguy:
its this one if it helps.

thm_w:
What FETs did you use? Were they included or did you source them.

Can you measure the voltage on the gate of each FET to see any differences?

MikeK:
FWIW, there is a thread on here (commented on recently) about upgrading that Chinese load kit.
