I used axial leads on mine but so long as the leads are long enough on those radial ones it should be fine.

I've just found that this project fond its way to the shop. I think I'll try to build it from what I have.
What would be the best input transistors? I have some Fets (sk170 and 370) and plenty of 2sa970/2sc2240BL and none of the 2sa992/1845 or mpsa18. I have plenty of BC550c/560c and 2sa1370-71E and 2sc3467-68E.
Instead of 2sa1381/sc3503 I'll use 2sa1406/sc3600 as I have enough of these.
Probably I'll have to get mje1503x as 2sa1930/sc5171 are not as powerful but I used them to drive triplets.
I'll appeciate any comments and suggestions.

Circuit boards are enough. Parts may come from anywhere, be it Mouser or B&DEnterprises (including hard to find transistors), DgiKey etc ort one's spare parts box.

Basically 2 monoblocks in a single chassis. The outcome is surprisingly good Ė someone on this thread previously used the term ďauthorityĒ to describe the amps performance and thatís probably the best way to describe it Ė it exerts tremendous authority over my speakers. The sound is quite forward with great low end performance and soundstage. If I compare it to my Arcam FMJ (which was a bit underpowered for my speakers) Iíd say it sounds the same (i.e. very neutral) but X 2 for the authority and ďsizeĒ of the sound. A very pleasing outcome and Iím dead happy!
Anyone contemplating the build I suggest go for it - itís a whole lot of fun but take your time, do it carefully, donít skimp on the Power Supply side and enjoy!
Very nice!

Would these work for D 4,5, 8 and 9? The build guide says any 3 amp diode, these are 4 amp.

Default Hello all....

Glad to see things are still going on !

I really did not mean to abandon the thread .... Much has happened lately.

My PC died , had to build a new one . Come back online , my yahoo email was hacked (compromised) for the 3rd time. So .... new quad core HTPC ,new house,
new ISP = no money for audio .

All is better now , found a pair of Mission 763i's and replaced the bass drivers.
Now I can REALLY hear the full fidelity of my badger prototypes.

I now just about have what I need for 3 amps.

1. Subwoofer amp - I found a 40-0-40VDC PS (below - free!!) This amp will be maxed out , all 3 pair , lower voltage (SOA 4amp per device). This amp will be "down and dirty" MJE340/350 VAS running at 12ma , have to run a 3.2R load in a sealed enclosure.

2. A new 2 channel full range amp. If I cannibalize my present amp , I'll have a nice shielded trafo , 40Kuf , and 60-0-60VDC to work with. These amps will use just 2 pair el cheapo MJW1302/3281. I just have to power the missions ,and my present power stage does so admirably.

I was very surprised to see the Badger actually reviewed . Integrated Amps: An Addicts Guide. - Page 7 - Product Reviews & Personal Opinions (Moderated) - StereoNET Australia
I KNOW this amp outperforms mass produced OEM stuff , but I was amazed to see it auditioned by someone who listens to $$$$ real amps !! Of course Niss's build was awesome and contributed to the outcome.

So , My Email works and has a VERY strong password . I am amazed as my former passwords were quite unique. Anyone spammed by my account ,I am truly sorry. In this increasingly insecure online world ,one must be MUCH more careful .

Ok, OS, I'll bite. Why amp bits on a cart with a box of kitty litter, cigarettes and a quart or two of oil?
