Hi guys, this is my first DIY electronic project and i have a ques re the res checks, so everything checked out except terminal 7 and B3, which is connected. I dont know if its my really cheap DMM, i realized for other terminals i need to hold the probe steady for a while (like 5 seconds) to get a reading. I did re-solder the joints at 7U and B3, i have a solder suction thing which im not sure if im using it correctly cos it cant really remove the solder on the joint too well, but still it doesnt check out. Think I will get shot saying this, but I went ahead with the voltage check, it was smoking , and had a few sparks coming off the unit when i first turned it on for the check, but after a while it stabilsed, and all the voltage actually checked out! and even better, it works and it sounds beautiful.
I am hesitant to go ahead with the speedball upgrade (partly cos it sounds so good already i dont wanna risk breaking it) which I also bought, so my question is, is it possible that the res check failed and voltage checks out and amp works? and i also notice the aluminium chassis gets really hot, like i know tube amps especially the tubes are meant to be hot but i think the chassis is almost too hot to touch is that normal?
