HI CHARLIE & ALL OF OUR 554 MEMBER"S...
A WHILE-BACK, I bought an all valve-amp ''head'' ''NEW'' At a bargain price, knowing it to be a modern sounding amp,very marshall-bright,but IT was so cheap $299.00 aud.. that I thought if not good I would use the tranformer's etc to build-up a more vintage-sounding amp...
I sent the schematic to charlie for his thought's & about 2-3 week's ago I decided to attack it ,I again emailed charlie for advice and to cut a long story shorter!!!!!,charlie started to send component ,value's & depletion's etc & I did the physical desoldering adding,changing capacitor value's here in OZ,,,
THE end result is to me a ''great'' 70th birthday gift from charlie!!!!!!!! AS the amp now has a loverly vintage vox-like sound ,with a top-boost option ,so it
has,,, the vintage,''normal'' &top-boost sound's at the press of a button & or optional foot switch ,[as yet to make a small pedal on-off x3 foot swiching unit] but as I am only fiddling here at home may not bother ]...,IT does have yet another o/drive channel [a 3rd switch[push-type] that bring's yet another ''triode'' into the circuit ,that is a fuul-on distorsion option that I will never use!! ,but it's there never the less...
NOW as to name the ''sound'' I will call the sound ''THE-CHARLIE-CHUCK-''HALL'' sound!!!..
THIS amp is now a trully ''international-unit'' designed in australia
by ''ashton'' built in china ,modified by'' UK-GURU'' and manually altered by an ''OZZIE''HA.HAAAR''...
THE siver mica capacitors arrived today charlie ,so I will repace those 47pf ceramic cap's with those & that will complete the project ...
MANY,MANY thank's for your patience & expertese & at least 25 email's !!!!!CHARLIE ..
AN appreciative ,ozzie........................barry..
