The Amp Garage

I downloaded LT Spice and created the V1a section of the SSS just for kicks and when I try to run the simulation I get this error;

"Unknown sub circuit called in xv1a n002 n005 n006 triode"

I didn't create a heater node, would this be the problem?

Triode model is Duncan's.

Thanks

It also only has 1 LNFB like the 80's ods (ie #124) Do you mean the 4 10M resistors and the 0.05uF cap from the plate of V1b to it's grid? Yes, from what I recall someone who had access to the amp wrote...it is somehwere in this thread.... http://ampgarage.com/forum/viewtopic.php?f=4&t=412&hilit=du...

With headphones actually noise is present but if I turn Pt or Ot 90 degree , the Hum noise go away!

With oscilloscope in Ac 20mV /div with trafo in line and 90 degree, se pics!

Which way were the transformers positioned with the noise gone?

Ha ha, me neither! I guess I'll be doing it your way!

That looks like a good option, thanks.

Sorry, I'm probably not being clear about what I'm asking. I have the same switch in your pic. But take a look at the pic I posted. See how your switch has only 8 terminals, the one in the pic I posted has extra terminals, the other side (common side) of the caps are each connected to these extra te...

Thanks for the reply but that's the one I bought. I had any extra pins cut off.

I did the low filter, and realized that I was 1 lug position off on the whole thing for the high filter :evil: So I'll need to do that one again. Here's the low filter. I omitted the 39K. I think I'm building something between a JM an a #002. I schematicized mhartman's layout(nice work!!) and it's ...

Aaron, I have.a pic in my Modded Bassman thread. The amp is nothing special. I was just obsessed with accuracy, it sounds fine so I'm going to leave it as per B's suggestion.

I got the schematic drawn up. I will get them scanned in tomorrow at work.

Did the schematic ever get posted?

Since nobody here has gotten their hands on SSS002 and 005 seems to be the only SSS that is known by members here, how do they operate when turned? Does the Hi increase or decrease treble when turned clockwise? And which position is bypass, 1st or last? Same question for the Low filter.

In my opinion there are other mistakes on the filters I think before them it should be like the attached If I did this with the SSS002, do you think I should place the 0.003 cap back to where it is on the Japanese schematic? I currently have it as per the May Contain Errors schematic. I would do it...

Good luck, let us know if you figure something out.

Maybe email Chris and just flat out ask him, what do you have to lose?
