Hi markusw,

did you do the simulation with different inductor values, e.g. 0.32H as opposed to the 0.65H. Would you think that the value of the inductor will have an effect on the Treble Filter response?

On the previous page I had the inductor set to 900 mH.
With 150k there is no difference between 320, 650 and 900 mH.
With 15 there is a slight difference.
In the chart below I stepped the inductor (320, 650 and 900 mH) with the high filter caps 360p and 20n.
With 360p the treble content slightly decreases with increasing inductance, with 20n the treble content increases with increasing inductance.
Don't ask me why :lol:

Thanks!

All in all can it be assumed that the 150k is not correct since there really is not much effect out of the treble filter. Can somebody chime in who has built a SS how effective the filter (treble) is?

It is pretty substantial with the SSS02 type setup. You definitely notice at at every click and full "on" and full "off" make a pretty big difference.

According to the attached pictures of SSS #002 - once posted somewhere in the internet - and according to the attached picture of SSS #001 - once posted here by some member - the layouts of SSS #001 and SSS #002 seem to be rather different - at least for my eyes.

And according to the attached picture of #001 and the attached schematic of #002 – once posted here by some member – at least the tone stacks seem to be different, too. Just notice the size of the treble pot of #001 and the two caps located at the terminals of the bass pot of #001.

In my personal perception there's always a rather obvious difference in tone when changing the filter-positions (treble-filter) of the original Dumbleland and SSS amps with filters I played up to know.

Cheers,

I was checking the gut shot of #01 posted by Max (above) and noticed that HAD added some goop between orange drops that were physically leaning against each other. Is there any reasoning for this? ARe there any issues if caps or resistors are physically in contact with each other in certain parts of the circuit?

I'd wager best guess is to stop vibrations causing the leads to break, the glue holds the caps to the board and each other. He did this on the big elytics in other amps I've seen as well.

Thanks Phil, your explanation makes sense.
