The Contessa CA-10 Mini Vibe seems to be the same as the New Music Guild CA-15 and the Bartell CA-10 Studio Amplifier. It uses the same tubes: (2) 12AX7, (2) 6V6, and a 6CA4 with a 12″ speaker. Controls include Volume, Tone, and Speed and Depth for the tremolo.
Hi-
I have a couple cool amps you would like to see-
Contessa CA-100
and a Studio Amp- I would love to send you pics, both amps are working, but I could use a schematic- thanks for doing this!
I have a miniverb Ca-20 that I would love a schematic for too. Thanks
