Say Muffman -one more thing: do you see any choke or reverb transformer on the AST? I haven't seen any in online pics.

screaming goo yo i really need to try a Swart!!!!

the shop i do part time at is to lame to stock them! angry

Please make this thread a sticky! it's easily the most epic in this section.

heh. Rockin' Banana!

i accidentally a stereo Atomic Space Tone setup oops



















well, not that suddenly actually, this has been in the works a long time.

The little combo is the same AST from previously in the thread - it's a standard AST with a bunch of NOS tubes in it and the modded back panel with the larger port and switchable external speaker jack.

The two parts in the stack are both a bit special - it's basically a custom AST Mk.II head, with some changes I requested, and a custom cabinet.

I've had the 2x12 cab for about a year now, it's the only one Swart has ever made in the AST color scheme, and the only one they've ever outfitted with Celestion Blue's

I've just received the head, which has been in the works for a little while. AST Mk.II #77 was once a standard Mk.II (which is the same circut as the original AST, with the addition of a bypassable, tube-driven master volume, and the addition of selectable output impedance, since it is a head after all)..... but I had some small changes made to it.

Because I'm using the two amps in a pseudo-stereo setup, I wanted the circits as similar as I could - the output impedance selector on the Mk. II means it is using a different output transformer than the Mk.I, so I had mine built with the original AST output tranny, foregoing the option to have selectable impedance.

I also wanted the original AST metal badge on the front of the head.... they weren't sure it would look cool or not so they shipped the amp with the normal plastic Swart logo on the front, and included an extra AST metal badge and some screws. I moved the original plastic logo to the back (where I think it looks cool) and put the metal badge on the front, and I'm glad I did, I think it looks killer.

But the most important moment came when I loaded them both up with the same tubes, used an A/B pedal to make sure they were both the same volume and tone and slight reverb level.....

then i turned on a bit of tremolo MY ASS IS BLEEDING

insane, totally hypnotic. stereo amping, I think I'm hooked oops
Babaluma
nice one muff, and it was even built in the future! applause applause applause

been eyeing amps again myself recently. not sure whether to just mod my champ 600, or buy a 5F1 tweed champ kit from somewhere and build it myself, or spend a bit more and get something by swart, emery or siegmund etc.

whatever it is, it has to be tiny and quiet, and break up nicely at low volumes for recording and japanese apartment living!

i've often dreamed of running my dimension c into two tube amps, it would sound phenomenal i reckon!
Moog$FooL$
my god man!!! angry angry angry

this thread is just mean!!

that truly is a beautiful set-up Muff. congrats!!!

Baba. i recently did some minor work on a Siegmund Midnight Special for a friend, & that amp is just incredible!! the workmanship inside is perfect.... i was afraid to change anything. i really didn't want to have to disturb any of the original wiring. i also had a reason to call Chris Siegmund & found him to be very interesting & nice.

this amp also had a cele. blue & sounds to die for!!

Why do you torture me so?

Why? seriously, i just don't get it

What did I do to deserve such taunting? Is it becaus eI'm trying to copy the awesomeness of the AST? I have most of my parts, still trying to guess at the circuit, but I think I have something that will work.

Remember this Muff: if you want some $cash$money$ I will pay for more detailed gut shots. The new AST's apparently all have epoxied circuit boards so you can't read anything.

Please sticky this Muff. C'mon she's beggin for it.

i have a feeling Swart has based some of what he's doing on the old Valco amps..... Supro, National, Gretsch, etc. along with Fender. starting with Valco circuits (there are many) you might be able to build something similar to a Swart. seriously, i just don't get it

lol, not trying to torture anyone, trust me...

I'm not sure about the epoxied circuit thing, I talk to the Swart guys fairly often and never heard anything like that. Also there aren't any circuit boards inside them, it's all point-to-point wired turretboard work. Covering that all with epoxy would be a huge pain in the ass.

Also, right on the back of the amp it's printed "caution - danger of fatal electric shock - no user servicable parts inside - take to a qualified technicican for service". If they epoxied the guts you couldn't take it to a qualified tech, you'd have to send it back to Swart. Anyway that totally seems to go against the vibe those guys have, I'd be amazed if it was true, where did you hear that? Are you sure you aren't thinking of Dumble amps? I know it *is* true about those beasts.

Anyway you have piqued my curiosity so I will take the head apart when I get a chance and take some pics for you - and I would not dream of taking cash for something like that, doesn't seem right at all.

Also....in the new head the reverb tank is bolted on the inside of the top of the cabinet, and is not bolted inside of the vinyl bag - making reading the markings on the tank very easy, I can let you know about that as well.

But I can't do any of that for a while as I'm in Sweden right now, only going to be home for about 30 hours at the end of this week, then off to Mexico City and then Brazil. But when I have some time at home I'll take it all apart for you.

The AST started with a Gibson Scout circuit and evolved from that....

posted this earlier in the thread, but here again in case you missed it...

.... this is the guts of the COMBO, not the head. I'll take the head apart when I get the chance.

Dude, that is ridiculously amazing. Happy & safe travels!

FWIW I have been STUDYING that picture of yours for about 2 months now (no I'm not joking!). It tells me a lot except for the actual connections and component values (well some are visible). I've got my Heyboer trannies, tubes, JJ can cap, sockets, turret board, reverb pan, and most of the hardware. All I need now is to order up the resistos and caps, maybe a better chassis. I'm going to have a friend build the cabinet close to AST specs too.

I found a guy locally who fixes amps and he said a client of his had a Swart AST. When the amp came in for repair, he told me the accutronics reverb pan # and he's the one who told me that Swart is using epoxy now. No circuit board of course, I meant turret board. It's been done before, and that's one tasty amp which people like me would want to clone so I wouldn't blame the guy!
Muff Wiggler
ok, i've been curious as hell about this epoxy thing, to be honest I was a bit ticked off about it, because I don't want to have to send my amp back to the USA if it ever needs repair.... IMHO one of the benefits of buying a handwired PTP amp is that it should be easy to work on by any competent amp tech if you have problems.

So anyway, I pulled the new head apart tonight and I'm happy to say no epoxy, just like my combo SlayerBadger!

although, somehow, wtf, the wiring has gotten even NEATER. Damn Michael Swart does nice work.

(super hi-res pics so please give 'em time to load)















Muff Wiggler
just want to put the combo and the head side-by-side in a post here so it's easier to compare them....

first the combo, then the head:



Moog$FooL$
nice stuff!!
that's pretty much how it ought to be.

not sure where the epoxy worries were coming from??

if you want to see really clean wiring.... look at a Siegmund amp some day.

I had an Atomic Space Tone- great little amp, and so warm- I kind of regret selling it, but hey those bills gotta get paid.

Looking at these pictures of the inside wiring, it's obvious that the work is impeccably neat! I am having soldering/ wiring envy right now!
Space Jazzer
These are indeed some mighty pretty amps...

Oh, and the play great, too!
