Thanks. Found a pack of 10 ST BD139-16 in Germany at good price.

Hi!
Does anybody have made Q17 gerbers that follow Universal Mounting Specification? 🙂 @Tim1999de @iTiberius
@stef1777 What are your Q17 turbo drilling sequence measurements in your Q17-TURBO-Drilling.jpg ?

The right drilling file is here : Q17-TURBO-Drilling.pdf
When you print it, verify that the size is ok. The size may vary depending on your printer. Otherwise, it is also possible to print the drilling plan from the KICAD file Q17-TURBO.kicad_pcb.

Hello,
Has anyone ever used this type of component? Is it reliable?
https://www.aliexpress.com/item/1005003088698456.html
This Ali shop is just as an example.
As I have a contact for TH switch (NO) on the speaker protection modules, I wanted to buy some to wire them. I already have another model of thermal switch but they are too big to fit under the PCB.

I don’t have a “reliability” report about these parts but I have bench tested them with a heat gun and the Normally Open (NO) parts close very close to their stated temperature. The softstart module I use has an over temperature shutdown, this (NO) thermal switch is mounted to the heatsink, should the temperature ever get to 70°C the AC power is cut off.
If the Q17 heatsink ever got that hot, we have major problems 😂.

Thanks Vunce.
For the main when used, I generally use KD301 or KD302.
I have this soft/start module in stock. Manage laching or no-lashing switch + led. Double main transformer output. Convenient when you have two transformers. Work fine and small size but no temp shutdown circuit included.
I expect an assortment of buttons to try to have something more beautiful than the basic button. I also received the logo. 😛

Hello!
I received a nice button. 12m with a nice soft green. CNC fab. It exists in other colors and sizes. It's a momentary TACT that makes a little click that you can feel under your fingers. It works directly with the softstart including the led. So I ordered a red one to compare. 😎

Hi again,
I found an amplifier similar in performance to the Q17, made by the Czech company spaudio. On the input they have a combination of 2sk/2sj, on the output also mosfets but I don't know what type. Power output is 200w/8ohm & 400w/4ohm, dual mono design, and uses 2 massive 750w toroidal transformers and 4U box. I also like the interior layout very much, that's how I would like to make my future Q17 as well.
It would be a very interesting comparison with Q17. Its price is at the level of 6000€

Quite the opposite of my straight-up version. 😎
By the way Tim if you pass by, what do you think of my problem with the BD139 "G"?
