the big one

So I'm toying around with the idea of building "the big one".
At this stage it is just an idea/concept so I'm open to opinions or suggestions.

I want to make a "V-8" stereo amplifier like some I have seen with a chassis that resembles a V-8 engine. The tubes would definitely have to have top caps so I could have "plug wires". I'm thinking since 6bg6 tubes are just a 6l6 with a top cap and are pretty cheap I could use a 6l6 schematic for PPP.

I already have a power transformer that will deliver more current than I would ever need at voltage used and I can get 100W OPT's from Edcor for about $110 ea.

I found this schematic. Looks easily doable.

Thoughts? Quad_6L6_PPP.gif

Hi, a friend and I were thinking along similar lines and I was even thinking of repurposing an aluminium engine block for the chassis. Another friend of ours is contemplating a turntable using a flywheel !

The schematic looks interesting i can't really comment on any issues as not an expert in this field however I am very keen to follow progress and learn or help if I can.
