SOLD OUT: PCE/Turbografx RGB THS7374 amps and cables

bump

I have updated the amp with output resistor values closer to the ideal values of 86 ohm with a 586 ohm to ground.  The ideal values can only be done with 4 resistors so have changed to the closest I could get it with 2.  Now using an 86.6 ohm resistor with a 604 ohm resistor to ground.  Both resistors are 0.1% tolerance.  See the math below:

Bump!

Are these still available? PM me!

since im no longer selling these, i shared the files if anyone wants to build there own

Nice looking amp, so how did it compare to turbokon's (http://www.tg16pcemods.com/rgb-amp.html) ? Just curious, even with discontinuing it.

[mickcris]

see the 1st post.  that amp uses 75 ohm resistors which make the output too bright.

Are you going to make more eventually? I think they are great amps and used them in my laseractive.

I dont plan on it.  I got sick of soldering them.  I was doing every one by hand so not the most efficient method.

console5 still has some kits if you are interested in soldering one together

or if someone on here wants to get some boards made from the link above and sell them pre built that's fine too.  I just got tired of doing it.

also, mobiusstriptech informed me of this earlier today

they should be selling what is the same thing soon (not that im really supporting these guys, but that might be the only option to get on pre-soldered since i'm no longer selling them).

the v1.0 circuit was an update to micro's original with viletim's brightness fix added.  then the newest version just swapped out the ths7314 for the ths7374 and made the parts smaller.  Its still basically the same circuit from the data sheet.

Man, that assembly line makes me appreciate even more what you were doing. 

I'm glad they are doing a bit of QA on them at the end but still, that video has some interesting comments going on.

Hello,

Can you share files?

Thanks!

Thanks!

I think MNKyDeth might have some more info if you try to PM him.
