Matt Hennessey's review [below] about ONE amp is not quite correct. Fountain built a number of different models.

I knew Alf Veart who was the design honcho at Fountain. He died a couple of years ago but he gave me all the schematics. Just as well because the amps come in for service from time to time.

They used EF86's in the front end (and for tremolo) and did get it right - a special rubber moulding to support the valve socket.

Have schematics for these.

Matt's Speaker Facts
By Matt Hennessey
“Old Kiwi Valve Guitar Amplifiers”

Fountain only made one guitar amplifier, the Thunderbird.

It was two channel with tremolo and rated at about 35 watts. This is my least favourite of the old Kiwi amps. The use of non-guitar-amp-standard EF86 preamp tubes and a two-plane hand-wired component layout make service difficult. Although I was only able to visually inspect one of these amps, I suspect their tone would be 'unique'.

If you have any information about these amplifiers please see How to Submit.
