Title: TW kometous 60w prototype
Post by: Roe on December 28, 2007, 12:41:05 PM
I'm boulding this now. I really enjoy it  ;)

got trannies from heyboer (HTS-8593 [PT], HTS-5526-1RH [OT] and HTS-7750-1 [10henry choke] and parts from nik. nik's chassis and parts are good. I think this is a one off amp or perhaps a prototype. It's pretty close to a real komet, but slightly different visually (and the filtering is a tad higher altough that can be easily changed when i get 80uf and 8 uf caps)

this build is influenced by the socalled astroid layout from theampgarage

I'm not going to sell this. I just make it for myself as I cannot afford a komet

Roe,

I've been looking over that layout and thinking of building it for a while now.  I haven't found a schematic and I don't like building with just a layout.  Please post pics and your thoughts of the circuit when you're done.

I haven't seen a schematic for this circuit.

Roe,

I'm following your build very closely.  Please give me a tone report as soon as the amp settles in.  This one will probably be my next build as a I have a spare set of trannies that would be perfect.   I'm assuming Nik supplied the boards for you.  Give me the details of the build when you get a chance.

Thanks

ChrisL

I got a schematic. send me a pm and I'll send it to you.  I'm in copenhagen for 5 months now - without my amps. so I cant report now. but when I and some tech friends fired here up she sounded loud and aggressive

this amp is alive and kicking. sounds like a cross between a TW express and a jmp50 with a vox cut control.
It sounded killer with SED C 6l6GCs today. I'm gonna install the ampgarage footswitch

Fantastic! can't wait to hear some clips.

What does the footswitch do?

Post by: Roe on May 05, 2008, 11:35:22 AM
it switches between fast and gradual mode. different attack and gain. from vintage to wreck

I'll be away for the next month so I cant post clips before the fall

We recorded with the comet yesterday. sounded excellent with a esquire and a strat.

however, it'll take a few months before the record is finished

the comet has become very popular in our studio and rehearsal room: it has been used for:
punk recording  (hamer korina special jr and 4x12" w g12t75s)
country recording (strat, esquire; 2x12" with alnicos)
stoner rock rehearsal (335 tuned to C; 4x12" with scumback H75s)
the stoner guitarist says he is gonna get a comet now :D

the second comet has arrived. will start buiding soon

the second comet fired up without problems. the bias resistor should be increased to 10k though to get the right bias range for 6l6s (not necessary for el34s, it seems)

Hello,

Heheh...It's Roe and the Komets!

Sounds like a good ole 60s band, with mop hair and thick plastic glasses and all that!

 ;D

Yes sounds like a good 60s band :D
Here's a clip of the first komet. the second amp (telecaster overdub was a 45/100):
