Default My new Chipamp.com LM3886 kit almost there...

The amp is finally making noise in its chassis. Its a Hammond 1402 - nice little unit albeit a little snug.

The xformer is an Antek AN-3225 300VA 25V unit...very inexpensive and seemingly nicely built.

I am feeding the amp with an Aikido 5687 tube preamp and the sound is very nice. It is very quiet-no hum. My other power source is a Tubelab SimpleSE currently running James OPT's and Gold Lion Re-issue KT-88's which also rocks pretty well - Jury's still out on the comparison.

All the other parts I either had on hand or got from Mouser except the heat sinks which came from surplus sales - very reasonable.

I realize that I am not 100% done yet...I still need to secure the toroid, fasten the heat sinks, and trim some wire. The only thing I am not crazy about is the position of the PSU board. I may see if there is enough room to flip it around and bolt it down to the top of the chassis...not sure yet...

It looks great. Congratulations!. Could you tell us what is the exact part number of the heat sinks you bought for surplus sales? They do have reasonable prices.
Thanks

These are the HSIFES50295 for $6 ea...cant find much cheaper unless you scavenge a PC or something...very good quality. These should be more than enough for a 2 channel amp listening at quiet to moderate levels.
