  Spent some time this week with the mill getting the chassis built for my Pete Millett Engineer's Amp.  A work in progress...
 
 

Very nice.  I've always wanted to build one of those (being both an engineer and a fan of Pete's work) but have yet to find a use for it if I did.

  XP-90 CPU cooler! Those IRF510s don't stand a chance...
 

 
 

Cool..., love the idea..

I am re-doing an old project :

@vixr: Somehow you've tapped into my mind and retrieved the idea's I've been holding for 3 years now. Seriously though I need some 1 inch thick smoked clear black arcylic perspex how much did you get yours for? My local retailer only has up to 8mm. But I've got plans for a $4.5k preamp project for a customer.
 
@Chris: The engineers amp is a good one had it along with my Jonokuchi (another of Pete's diy if you hadn't known). Good stuff indeed before I flogged it for cheap.

DefQon,
    I got mine free from the scrap bin at work...I bet its pretty expensive.

Here is my latest HP amp: 6AS7 with Sophia Electric Mesh Plate rec.tube - 274B. This build was inspired by the Woo Audio HP amp which can be purchased with the same rec. tube.
 




 
Take a look at the write-up: Sanguine

Here are a couple Oatley K272C portable triode HP amps I built up from kits.





 Take a look K272C

@vixr: Luck you
 
@houston: Good Lord that's a nice looking build but isn't the chassis a bit too small? Especially the power supply enclosure?

 

[mwhouston]

@DefQon: the chassis for the PS did get a little tight but I like working with these cast Al enclosures because they are solid and I get them cheap from work. There was plenty of room in the amp section. I'll post some images of under the bonnet.

this looks awesome! thanks for the link...

It's great to think you can have your own portable triode HP amp which runs on a few batteries. I think the K272C is the best so far. Some like the K272 original because it ran on one 9V battery. But I have had a number of every model including a K272B which never made product. I got an early prototype. The "C" is the best sonically.

Here are some under the bonnet shots of Sanguine, the 6AS7 HP amp. It was mentioned that the the PS chassis looked small. It does get tight but workable. In the PS note the 4uf PIO Russian cap (big brown) and the mains power filter at the opposite end.
