Smile Hi from Canada

HI I am a newbie at this hole thing, forums and amplifier building so I will make mistakes for a while. I live just north of Toronto. I am an automotive tech by trade and doing this as a hobby. I am building two of Randy slone's Opti-Mos amplifiers. I have built both modules and speaker protection board and now am going to order my power supply. I will post some pictures when I figure out how, if any one would like to see them?

I would like to see some pic's of your project, I have G. Sloan's book but opted to build some Pass Labs Alephs instead. Did you purchase any PCB's or other parts form Mr Sloan?

Cheers,

Gaucho

My Pass Labs project (Aleph 4 built as mono-blocks) still reguires completion of the cases as they need top covers and face plates. They have been up and running for awhile now. I built it from the service manual schematic taken from PassLabs.com

Your amp looks good. Did you pirate the case from a comercial product?

The case I'm using for now used to be a 5 disk cd player that never worked good from new, the aluminum plate is from a car amp. My plan is to build a 1.2 KWatt RMS 6 channel monster amp in one inclosure.

Do you have any pictures?

Pat

Here's shot of one of the channels. I slapped some angle aluminum together to make some poor man's heatsinks it's a little crude but it works.

Gaucho,

Thatís pretty cool, must have taken you a long time to build those heat sinks. I read the manual you posted and wow that amp runs hot!!! How does your amp run with those heat sinks? Shipping weight 110lbs??? You donít have much to finish it. Are you happy with it?
