Sameish. The loop is not the same. With the loop bypassed, fat bypassed, and the deep switch off if on the rack unit, I could see them being exactly the same.

The other amps companies list above that use heyboer each of those amp companies tells heyboer the design the have to make the heyboer transformers the way they want that heyboer transformer

Right the effects loop was updated for the better also updated that Mike Soldano wanted to do longtime ago was DC heaters

I have no issues with my newer version of the 100 Rack. It's the first amp in many years that I love playing through and have no intentions of selling it or changing to something else.
I have a friends pre-Bad SLO here that I just repaired and it sounds great as well. I enjoy playing through it.
I'll take mine any day of the week because of the master volume and ability to switch channels from the front panel as well as the depth switch mod.

In any case, a SLO is a SLO....you either love it or hate it.

Ive also read that the new bad slo circuit is not the same as the og.. further, that the bad rack unit however, is the same as the og circuit ? anyone confirm?

There are very small changes here and there but for the most part, the same.

For example, they use a 220k plate resistor on the second OD stage instead of 100k like the OG. Why, I don’t know. Maybe they wanted it greasier with more gain. Or lower voltages for tube life. Not sure.

The treble cap is 500pf instead of 470pf. Small things like that.

Then you have Omron 12vdc relays instead of LDR’s. That will make a small difference.

The loop is also different, as already mentioned.
