You could assemble a classic that will last a long time or do a quickie

 

[OnAudio]

If the case is worth $270, whats inside should be worth at least the same

So your amp could be worth ~$1000.
A break down
$20 * 20 hours = $400
Parts = $540
Friend come in listens and loves it , wants it = $ ?

Thank you. You just need TIP142. Will work in 2 Ohms assuming this is nominal. Keep us up to date. Enjoy your build.

Decided to bump this a bit so that members can share their progress pics and exchange stories round the camp fire about 1DIFFQC first notes

Hmmm--- Not happened alot. Just picked up a old Nad 216thx amp. Will take out the internals and populate some 1diffqc boards and make them fit into the chassis.. Well that is the plan.

Well i got my transformer and all the power supply boards but since my truck is almost dieing on me and holidays coming up this is taking the back burner for the time being.

Harrison,
I have to admit that my boards are sitting 98% completed and I am still waiting to get to where I have a pile of transformers so I don't have to purchase more. I will be getting there soon and will complete the first project and then start on the other set of boards you sent out, the simple model amplifiers.

Best wishes,
Steven

Hi members,

Looking forward to your feedback. The target was roughly 30,000 reviews. The feedback will include noise which is useful such as mood, weather, humidity, magnetic pull, orientation from true north etc

Dear Harrison,

thank you for providing asc files for testing. On opening it there are many missing symbols. Are you able to provide it too (except Cordell-Models.txt which are to be downloaded from Bob's homepage)?

Thx, Toni
