Well, I wouldn't go as far as saying I am "quite experienced" at buying parts online, I buy mostly from the main stream electronic suppliers like digikey and mouser. Sure, I wouldn't mind taking an active role. Just let me know what end of the group buy you want help in and I'll see what I can do as far as sourcing parts. PM me with the details.

I am interested, as long as it is all quality parts.

pappucho - we need top quality components for this list here :-

we will need all that x 2 because this amp has two boards.

Right now I think we should limit ourselves to the passive/active electronic components. First find good components and find a source that offers bulk discounts.

then we can focus on finding out about the other stuff (psu etc.)

Cheers!

gsferrari,
Sounds great. I would also vote for quality components, nice caps etc...

I don't really need the hookup wire as I already have 100ft on the way from the wire group buy... I have a stepped attenuator on the way, a resistor group buy for this might be cool... as for the PSU's... might not be good for people who want to try their hand at a dynamite when kevin releases those specs...

 

[gsferrari]

ok then its just for passive/active components then.

Any suggestions for where to source these from? Ive never bought stuff online and now is as good time as any to begin

Cheers!

I'm definately interested, especially if someone can point me in the direction of a couple of boards.

 

[gsferrari]

Zemo is selling his boards for $20.00 I would approach him. I am taking one of the attenuators and all the transistors off him. You are welcome to take the other attenuator from him.

Cheers!

Got the Hammond RMCS190313BK1:

Decided to get one large enough (17" x 13" x 3.5") for everything instead of two separate and smaller cases. The $97 price I quoted included shipping.

Are we go yet? I am getting impatient here and wanna order parts asap. Whoever is interested hands up because I will order parts before this weekend - you are either in or out.

Guys remember also to check the BOM and parts list that BCBill generously posted in the boards groupbuy thread, certainly very helpful:

I am in, depending on prices, for up to 6 boards worth of components

3 amps, raif? Does that mean you're building units for others? If so, shoot me a PM with details. I might like to get one of these, but my DIY skills aren't really up to snuff
