Calling all Asteroid builders....

Post by wally19840 »

I am starting to recieve parts for my Asteroid K60 build and I am asking anyone that has built a K60 to ring in and comment on their experiences with building this amp. Any advice and comments are welcome and I hope to hear from as many of you guys as possible. I have already had some help from a couple of guys here. I will also try to keep everyone informed on my progress as well.
Thanks in advance,
Wally

I've built two of these. they are much easier to build than the express. I used the layout and pics of a real komet and never had any problem except upping the bias resistor to 10k

I'm still in the throws of building mine.

Little things like the SS stand-offs have made me lose focus.
I couldn't get the board heights verified or the size thread
used for the stand-off screws. There's height limit to the stand-offs
with internal #6-32 thread spacing the dealers sell and 1-1/8" was on no one's list. When I decided to stack an 1/8" spacer on the 1" piece,
I happened onto an 8'-0" length of internally threaded SS rod that
I could now cut into correct sizes. Today I'll go buy the Dremel cut-off
wheels to finish this amp.

It's been an expensive mutha to build maintaining the parts quality
seen in the originaals. :wink:

I got my kit from Barry Witt and he painted the chassis, assembled all the parts and threw in a whole bunch of extra parts. One heck of a nice guy sorry he left ampgarage for a while. I also got a CD with all the data I need. I have to say this amp is no where near easier than build any of the Trainwrecks. How do you figure that. I haven't even begun to figure out the coiled wire. I have been so busy with my other builds that this one is still sitting untouched. Having the cab built by Larry (distortion) right now. Heck I should of had Barry finish the rest of the build.

I enjoy building amps just this one is not as familiar to me. :)

Does any one have an extra set of trannys for sale for this amp. Just asking before I try to source mine from Heyboer in case someone wants to sell a set.

Sure, what would you like to know about?

Be advised, I have a few unanswered questions regarding this amp's construction.

Is Heyboer making your XFMRs?

I built an Asteroid, but used an Express OT. What are the proper specs?

I'm just bumping this thread since you other Asterhoid builders aren't really
chirping about your builds.

I'm also trying to make this P & S camera's learning curve a little flatter. :roll:

Here's where I'm at:

here's three big pics. they have been posted before. http://www.hf.ntnu.no/hf/filosofi/Ansat ... dal/komet1

http://www.hf.ntnu.no/hf/filosofi/Ansat ... dal/komet3
I've since changed the 100uf screen caps to two atom 80uf caps. I recommend sylvania 6ca7s and a mullard gz34 for the komet 60. also I like a cv4024 in v3, a rtf ecc83 in v2 and a tungsram ecc83 in v1. the amp sounds absolutely killer

I am done but need to wait until the snow storm blows over to get the 3 amp and 3/4 amp fuses. I also need to get another set of tubes but I will borrow from my express for startup.
