Title: Hot Crack
Post by: BJK on March 12, 2021, 06:42:01 AM

I recently performed the speedball upgrade to a fully functioning stock crack (All voltages checked). After the upgrade, everything checked out fine (voltages and resistances were within normal variances). Everything sounds great!

one thing I've noticed is that after it's been on a whlie, it is VERY hot to the touch. The transformer in particular is almost too hot to touch. I don't know that I could tell you if this was happening before or not. I might just have now noticed it. Is this normal?

I've been listening to it with no complaints for several hours each day.

If the voltage measurements are correct, then the amount of heat generated is also correct.  There is a rather substantial difference between the maximum safe operating temperature of the power transformer in terms of preventing the power transformer from failing vs. running it cool enough that it doesn't cause problems when people touch it.
