Found or No Longer Wanted WTB WG K6100 High Voltage cover

here is a decent heat sink i used on an old defection board design turned audio amplifier. it even has a name brand on it lol
too loud for the phone microphone so there is massive distortion


Did you ever sell that deflection board, do you still make them? Looks like a great size for smaller monitors.
 
No idea who this is.

That's jetusenet here on KLOV.
In the past, he has also advertised these for sale on this website and not just Ebay.

I only made 5 or 10 and i gave the rest of the blanks away. i have few deflection board designs i will post a few pics now. there were a few minor errors as it was just a prototype but the picture looked great. somewhere i have a video of it driving 2 yoke coils at once. i only put that amplifier on a woofer to calculate the true RMS wattage of that woofer across different frequencies. i have several projects finished but rather than sell them i move the next project.

They didn't 'add holes' they went the sensible route and used a low cost off the shelf perf metal and bent it.

Umm.........duh????

Of course they used perforated sheet metal to manufacture it!
I meant they added holes to the fundamental electromagnetic design.

You're just picking fights now. Quit being so literal.

Having it laser cut is excessive and unnecessary.

I agree with that statement.

I make no assumptions, what you said made no sense.
 
I've never seen someone love their own name so much. Its so fucking weird.
What I find weird is that someone CARES that someone else loves their name so much...

Which is more weird? Loving your name or finding fault in others loving their name? You decide.

the good news is the company i used to produce these cages and covers for me do not charge extra for additional complexity of design. i could have the Monalisa cut into that sheet metal at the same cost of a single hole. and since my covers are the cheapest on the market you could assume my production cost was low as well.

Did you ever get the class D to drive bigger displays? I played with them on 9" MAC tubes with some luck. When I tried to go to the bigger yokes I could never get the output filters right.
I didn't know what I was doing and that didn't help. :ROFLMAO:

i made a different pcb for 19" tubes but never ordered it. as you can see my pic was not perfect either. well if i were to decrease the picture size even more it would fix its self . basically the same issue i am sure you have encountered. one issue is i did not find a cheap out of the box chip that sampled as fast as id like and to design that circuit from scratch meant more parts to assemble on the pcb. Sometimes a better method in theory is negated due to an increased number of failure points. if you have any ideas of a good/cheap chip i would be interested.

I had bought several class D amps off of ebay and was messing with them. I had one rated at 300w and one at 500w. One used TI TPA3255 and one was an Infineon chip. These were made to drive 2-4ohm loads (I thought that would be close enough) and that may have been part of the problem with matching the output filters.
I was looking for a solution where I could buy boards already in production and then modify them. Not having schematics and not having a sound understanding of the class D design made it much more difficult.
Class D would be a great benefit to the vector world if sorted out. Despite all of the abuse I put on these boards I never burnt one up. I can't make that same claim with factory 6100 boards. :ROFLMAO:

the more we talk the more i like your style lol
 
Build your own Class D amps!

I had a student team who tried to build my theoretical 10 kW Class H hybrid amp.
They got surprisingly close to making it work. They just ran out of time waiting on multiple parts orders.
