[Harp-L] Mystery amp question and sound clip

[John Kally <jkally3@xxxxxxx>]

Hi guys,
I just picked up yet another amp last weekend at a yard sale for $20   
(actually a buddy called me up because he saw it and thought I'd want  
it for that , glad I did).  Anyway, no manufacturer, the speaker is a  
1957  (or 47 but I think 57) Quam.  Anybody seen something like this?  
Just curious. I got it  with a Supro steel but I don't think it's a  
Valco product.
I think it sounds pretty cool as a harp amp. two old octal preamps,  
one 6v6 and a 5Y3.  Since I'm on spring break from school and just  
started messing around with Audacity free  software I thought I'd  
stick up a little example of how it sounds using an old brown shure  
with a crystal element (sitting on top of amp).   The playing is of  
course just me messing around, at least one flub I should have edited  
out if I knew how to do it,  intro to an old Cotton tune and the rest  
is just some random  little licks. No effects used and no animals  
harmed during the recording although my dog did go into another room.  
Actually, the recording itself came out OK with just an SM58 some  
distance away from the amp since I wasn't using a mixer.    The  
speaker is definitely going out, you might hear some of that in the  
sound clip.  And the tubes, caps, etc are all original or at least  
pretty old , I didn't swap anything out yet.

I'll leave this up for a couple of weeks as it takes up a fair amount  
of my limited webspace.
