Hi folks,

I got a chance to try out one of the new Gobo chip amp kits from Boxed Kit Amps: https://www.boxedkitamps.com/gobo-stereo-audio-amp-kit
Attachment:
Gobo-LM1875-Amplifier-Kit.jpg

This is a real smart looking LM1875 IC amplifier kit, about 15W. I really like the enclosure. It is a piece of acrylic cut with what I am assuming is a laser, so fine and accurate into an accordion like hinge that allows you to bend/fold the plastic over to form the enclosure. The kit comes with good capacitors - Nichicon Muse, Panasonic and Wima, and like most chips amps sounds good. The step-by-step instructions are very detailed making this kit ideal for a first time amp builder who has only soldering skills. I snapped quite a few photos of the build and will get a review of the kit posted soon.

Cheers

Regular price is $195US but the amp kits are on sale this summer (not sure for how long) for $100US which is a real good price IMO.

BTW, here is the kit link - https://www.boxedkitamps.com/gobo-stereo-audio-amp-kit

I should have a review of the amplifier kit posted in the next day or so.

Cheers

Hi, It looks like a bargain. I would pitch the "Alpha" pot for a good Alps. I have had rather poor luck with Alphas. Noisy and not well matched channel to channel. Then again swap in a fixed resistor and use an external preamp and solve the problem.

Good listening
Bruce

I too was a bit leary of the Alpha pot which seemed "lightweight". Once together is was quite and tracked fine.

BTW - I have the review of the kit posted on the main site now.

Thanks for the review Gio. I was looking into how I could begin to pursue building my own amp with no knowledge of doing so, and this kit seems just the place to start.

Do you or anyone have any suggestions on literature for an individual with limited to no electronics knowledge to learn more on how amplifiers work and how to build them?
