Power Output of J595 "Frankenstein" Kustom Head [message #24388] Sun, 17 January 2016 20:46   GaryLC Messages: 52 Registered: December 2012 Member Hi guys! I have a charcoal "Frankenstein" Kustom head, really nice condition, but have a question about it's output. From what I understand, these were the early equivalent of the Kustom 200 heads. This one has lovely tone, but seems to be about half the volume of my Kustom 200 heads. Other than that, the tone controls & volume operate fine. Is this normal, or is something ot quite right with this? Thanks!! Report message to a moderator

They were rated at 100 watts into a 4 ohm load. What speakers are you using with the amp? A loss of power could be caused by any number of things, like a the wrong speaker impedance or a faulty power supply or a bad circuit component. I would expect it to be close to if not as loud as a K200B head. Maybe one of the other guys will have a better feeling for comparative volume. Report message to a moderator

I only use a K50 and that is 25 watts and can play anywhere with that without a mic in front of it. Report message to a moderator

My own amp when I got was down to some 62 watts until I corrected it, then I was getting a much more correct 92 watts of clean power. Report message to a moderator

I've used it with a few speaker cabs, right now with an old Kasino 1-15" 8 ohm cabinet. I also have two Kustom 200 heads, so I can A/B all of them. Both 200 heads are considerable "louder" than the Frankie. It has great tone, no hiss, just not the power..... I thought that too, that it should be comparable to the 200 heads.

I have a good local tech that I'll take it to, just wanted to verify that something might be "off" before I did! Report message to a moderator
