[Harp-L] Sonny Jr watts. UNDERCLAIMED
All these years I have not really given a R.A. about watts so have been
doing myself an injustice by claiming only 40 watts on my Super Sonny or 410.
My Cruncher is 35 watts (34 with 12AU7 preamp). So if it's WATTS you want,
get your Super Sonny which blasts all other amps by pushing 55 watts if
setup the way that TRUE ENGINEER WITH A DEGREE Keith Robb has calculated. Him
methods of obtaining the final numbers are THE way to get an exact reading.
So NOW these last Super Sonny's prices will be reasonable, but I am not
going to sit here and screw myself anymore and under hype my amps. All I get
for reviews are: " You didn't give yourself enough credit for this
fantastic amp ( whether it was the Cruncher or Super Sonny ), this amp has the most
attention to detail over any of the XXXXXX amount of amps, boutique or
otherwise, that I have ever owned"... THAT is what I hear from my customers.
So here are the watts and how they were obtained by Keith Robb.
The specs for Cruncher and SJR410 are with all 12AX7 pre and a GZ34.
Solid state rect I don't have, but for 410 or Super Sonny was 55 watts.
Cruncher Stock uses a GZ34 rectifier. Super Sonny a 5U4 so 5 watts less, FIFTY
WATTS...
Crunch = 34 watts
Super Sonny or 410 = 46 watts by
using 12au7 drops the clean RMS watts, but not the peak watts much.
HOW WATTAGE RATING IS DETERMINED FOR SONNY JR. AMPS:
The amplifier is hooked to the specified speaker load, with a sine wave
applied to the input. An oscilloscope is hooked across the speaker load. The
volume on the amplifier is increased until clipping of the sine wave is
seen on the oscilloscope, then rolled back until well below the clipping
point. The AC signal at the load is then measured as voltage with a "True RMS"
rated meter. The result is squared and divided by the load in ohms to
arrive at the power of the amplifier in watts. The watts ratings are good for
all frequencies from 40 to 10,000 Hz.
If you want a Super Sonny I suggest you order now, even though I may if
demand is so strong build for those that just HAVE to own one, and still NO
ONE uses NOS AMERICAN Paper in oil caps military grade.
Call for pricing no matter what the site states, it is undergoing a
massive overhaul. I look forward to continually servicing such a great community,
worldwide. This week amps went to Malta, Alaska, UK, just recently Czech
Republic ( his review is up on Cruncher )... Thanks Rick, here is my truth.
I just always was more concerned in what you could actually hear, which is
LOUD If you need it that way, I fully describe in the manual how to get
more projection which means sound will travel deeper into the house. Anyone
or company that knocks my manuals or extra tubes obviously are not pro
players who have done the grind on stage for 20 years. Delta Blues Band, Sonny
Jr. and Code Blue band. I offer all the answers from a professional
perspective.
Sincerely, Sonny Jr.
