I just got one of these = cool design. Intention is for the output stage for a pro guitar amplifier (Hybrid tube front end [ http://www.londonpower.com/catalog/product_info.php?cPath=15&products_id=70 ] with the '200 output. I also got one of these to go with it: http://aussieamplifiers.com/lsp1.htm )

Hi All
Here is my latest Amplifier the HPA-nxV1200

An externally hosted image should be here but it was not working when we last tested it.
Very nice looking Anthony. How have you found mocing to SMD? I assume you do the assembly by hand?
Hi Bonsai
Thanks for your kind words. A couple of years of work has gone into this design.
Regarding the SMD, I have my own computer controlled reflow oven.
So all I have to do is stick the components onto the solder paste and it takes about 3-4 mins to go through the temp controlled profile and hey presto a perfectly soldered SMD board.
The remaining hole through components are done by hand of course.
I will be getting these professional made in the USA.
I have made some good contacts there.

Nice compact layout - neat.
Did you make your own solder paste stencil?

Brian.
Hi Brian
Thanks, I did not use a stencil for this amplifier.
Just used a tube of solder paste.
and applied it hand.
Stencil would be very handy if I was making 5 of 6 at a time.

Mighty, mighty powerful looking = >> 1K watts?
Can you find gold plated stab on connectors for that? ...
I ran into a mounting question for those MOSFETs ... the holes are japanese diameters (metric), so all the pretty #6 brass screws I have won't quite fit. ... Not really a problem if you have a source for 1.5 mm brass screws (is that the right dia.?) ... But, here in the states, that's a peculiar happenstance = not available @ Ace Hardware ... 😱
Awesome mate!
Well done on the construction 🙂
The whole amplifier looks great!
Please email me these photos and comments and I will post them on my web site Gallery...😀

And very nice amps.. 😎
I have a question .. I have 2 HUGE amps coming (160lbs) and
if for some reason unforseen , I can not restore one of them
I have recommended your modules (Nxv 300 /500) as a
worst case replacement.(he prefers the original class A)
These amps...

Have 2 -1.5KVA+ trafo's with 100k+ capacitance at +- 72V.
If I can't repair the first one , the owner stated that he would like
to make a super powerful dual monoblock out of it.
If I am successful with #1 , he actually has a third unit that
he would like to do the same modification to.
the thread is here..

I am just on a fact finding mission to see if pricing/ compatability
is reasonable for a PS of this size and is the topology
in these NX's similar to your earlier designs (av400, etc).
I did recommend your amps, so if you respond it might make
the customer more receptive , even if this modification
is only done on his 3'rd amp.
PS . I will have one of these as well..
