The next batch of Amp Camp Amp kits is now live in the store. We hope to announce news in regards to the matching enclosures in the next few days.
ACA/DIY stereo pics
Hi All,
Here is a picture of my completed stereo system. It includes a pair of ACA's on sleds that I built from poplar. The speaker cabs are home built. The drivers are Fostex. There is also a Bottlehead Quickie. My wife insists that it is an eyesore, but she likes it right where it is.

Are just the pcb's available? I go to checkout and there is no shipping method available to select. This stops me from checking out.
Where are you shipping to? Country, state, post code / zip code? Perhaps try again - I just checked and it's generating shipping options for US and international addresses.
Do you mean the kit without the chassis? If so, we can sell you that certainly. We took it off as an option to make ordering as simple as possible, because nobody was ordering "just the parts (and PCB"). Contact store support and they will sort you out.
Jason,
Yes I'm interested in the PCB and parts only, no chassis or heatsink. I'll contact store support.
Thank you,
Matt

Hi Jason,
I received my kit and have finally stuffed the boards. I was wondering if you could tell me what taps would be compatible with the included spacers as I need to drill the heatsinks please?

Amp Input Possiblities
Which types of inputs will drive this amp...
Preamp? Headphone output on MP3 player? CD Player Line Out?

A teacher once told me that there are non dumb questions. Of course I never asked her the one above. Since there is no source switching or volume controls, a CD Player Line Out is out. Doing some research I found that "A preamp output normally needs to drive a load of between 10,000 Ohms and 47,000 Ohms..." with headphone outputs driving as low as 30 ohms. Looking at the circuit I see at least a 10K ohm load so I think it's safe to assume that to drive this amp I need to use a preamp.
It's called learning. You've made an effort, so that's great.
Modern sources should drive this amp just fine without need for the gain found in most preamps. You just need to add a volume control (As simple as a potentiometer) and a source selector if desired. A B1 is a nice follow on project. It will buffer the source from your volume control (or volume control from amp)
If your CD player has adjustable line out levels you can use it directly.

The B-1 buffer, a Pass project. There are other variants, with names like DCB1, but the original is https://www.passdiy.com/pdf/B1 Buffer Preamp.pdf
