In light of the questions and postings concerning the power output of Kustom amps I am reposting this info from test that a performed 4 or 5 years ago.
I tested into a 4 and 8 ohm resistive load, in regards to the latter metal face amps where the plastic speaker jack tag stated 6 to 8 ohms I could come up with no easy quick solution to test at the 6 ohm load.
That being said though the wattage output seen at 6 ohms would fall right inbetween the 4 ohm and 8 ohm results.

K100-1 power into 4 ohm load.
Voltage = 13
wattage = 42.4 RMS
Voltage peak =17.8
Wattage = 79.2

K100-1 power into 8 ohm load.
Volatge = 19.97
Wattage = 49.8 RMS
Volatge peak = 27.85
wattage = 96.9
------------------------------------------------------------ K150-4 metal face circa 1972 into 4 ohm load.
Volatge = na
wattage = 61 RMS
Volatge peak = na
Wattage = 104
K150-4 metal face into 8 ohm load
Volatage = na
wattage = 79 RMS
Voltage peak = na
Wattage = 105.8
------------------------------------------------------------ -----K200B-1 (non effects model) into 8 ohm load
Voltage = 22.9
Wattage = 65.5 RMS
Voltage peak = 32
Wattage = 128
K200B-1 into 4 ohm load
Voltage = 18.64
Wattage = 90.2 RMS
Voltage peak = 27.1
Wattage = 182
------------------------------------------------------------ -----K250-1 ( non effects model) into 8 ohm load
Voltage = 26.3
Wattage = 86.4 RMS
Peak voltage = na
Wattage peak = NA
k250-1 into 4 ohm load
Voltage = 21.6
Wattage = 116.6 RMS
Voltage peak = 29.9
Wattage = 223.5
K250 (with reverb and tremolo) into 8 ohm load
Voltage = 25.5
Wattage = 81.2 RMS
K250 (with reverb and tremolo) into 4 ohm load
Voltage = 21
Wattage = 110 RMS
Volatge peak = 27.8
Wattage = 193.2
------------------------------------------------------------ -----
Frank head ( non effects model) test into 4 ohm load
Voltage = 19.11
Wattage = 91.2 RMS
Voltage peak = na
Wattage peak = na

I hope this clears up the questions for some of you.
I will post the test results of a K200A model fully loaded with effects Next week.
