I'm surprised someone has not yet made a fancy drop-in control board for the ADS200?
It is simple 24V transformer, albeit of good quality.
Awesome. I think I can cram a https://www.mouser.com/ProductDetail/Triad-Magnetics/VPT24-4170?qs=sGAEpiMZZMvwUzoUXIIvyTw34uqMHR%252buIg1%2f%2fV2UEN4%3d
and then drill some holes for the DPDT slide switch.Be aware that putting that 4.1 amp toroidal transformer into the case, may cause an increase of ~2 volts AC and present up to 40 volts DC at the regulator (max allowable) and likely require a larger heat sink.. To avoid cooking the regulator with your new transformer (and maybe the whole PCB), drop the input to the regulator by 5 to 10 volts. You could do it easy with a series string of 1N400x diodes or a 7805 and a 10 ohm 2-watt resistor in current limiter configuration.
The default Pace transformer presents 33v to the regulator (at 120vac line) and almost 35v (at max 126vac line). Too close for comfort.. There's plenty of room for a larger heat sink (see attached pic)

I made my own that uses a buck converter + LDO instead of the linear regulator with heatsink. I also switched to a TFT screen so I had to make a new front panel. It's been taking forever to finish the firmware since I don't have a lot of free time for it.
Is 1.4 now the current firmware?
Also, I have not seen any discussions on this recently, but how has the tip/holder redesign worked out? I remember that some early adopters were having trouble w/the gasket in the handle coming out of position and causing the tips to not fit properly--was this completely resolved?
There are a lot more things that go into the cost of a product than the parts, or even R&D. Logistics, design validation, certification, overhead, marketing, warranty fulfillment, and doubtless many more I’m not even thinking of.
Yes,yes, please go ahead and do it and share with us how it goes, and do not forget about plating the tips your fun project will be worthless without.
Obviously the margin has been cut the be more competitive with Hakko etc. So they reused the basic design of the old stations. Though, not sure why they didn't use a dual voltage transformer? Maybe has to do with protecting foreign markets? But then again Euro price sheet shows nearly identical prices. I bet Hakko does it for that reason.

Yes it's kind of baffling. They would need to stock 2 different SKUs (and they are smart enough to turn their 3 buttons into 1 assembly??) and deal with all of those supply chain problems with sourcing 2 different transformers from their supplier.
My guess is that they don't sell a lot of the 220V version for it to be worth spending the extra cost on the 110V version to have the extra winding. Of course, it's a chicken-and-egg thing: if they built a global version perhaps they could sell more globally...
I generally wonder why they bother with linear transformers when 90-120W 19V SMPS supplies are ultra cheap due to the scale of laptop manufacturing. Noise?

Man you need to be less of a dick. In fact, Unisolder shows that it can be done by hobbyists.
Leverage the difficult-for-hobbyists hardware (tip fabrication, hand piece) part built by others, and exploit cheap manufacturing of PCBs + shift burden to software which is quick to iterate.
There's a reason most American manufacturers died off, they couldn't decouple their slow-moving processes from processes that needed to move faster. I hope Pace can keep up and isn't kept alive by "buy American" diehards like me.
On Dave's teardown it can be clearly seen that 230(240)V version has two primary windings in series. It doesn't have 120/240V switch but trafo is universal, at least that one was...
Where is the firmware history for the ADS-200?
This fellow upgrades from 1.2 to 1.3 to stop temperature display readings from wandering around.
It's a socketed PLCC MCU swap.
