about that wooden door, that one is made out of hardwood, and there are lots of shops doing those here...
Thanks! Maybe germanium transistors? It does have a great sound to it, to my ear.
cheers

Hi kamranyousaf,
Please do a search for that amplifier. Most of these amplifiers have builders threads and a little checking on your part will get you everything you asked for.

An externally hosted image should be here but it was not working when we last tested it.

Not an amplifier but product will follow. My effective 2 bulb current limiter for testing new projects.
It has x2 48 watt halogen bulbs inside and can be switched to use only one bulb, or both for larger power supplies. Built using spares I had lying around.

Try to do something to improve the safety of the single insulated mains wiring to the plug top and socket outlet.
Mains wiring should be double insulated.
The OUTER layer of the double insulation get clamped INSIDE the plug top and INSIDE the socket outlet.
All the cable between is full double insulated.

You are absolutely correct Andy. A nice dose of flexible heat shrink had been added since taking this picture and it's now much safer and ready to be used.
This is a great design. Very well executed. Is the rear a pub below the amplifier modules or have you done point to point soldering on it? Very nice work.
nmos200 build
nmos200, 330AV transformer, slow start, VU meters, DC protection with MOSFETs
Previous nmos200 (a prototype) will go to another room 🙂
DC protection, slow speakers, subwoofer out, headphones out, speakers on/off switch board.
UPC 1237, Mosfet SSRs with photovoltaic couplers.

Great looking build minek123 - and pictures. Lots of electronics packed in that very nice looking case. I've used many of these types and pretty much love them in all their variations. 🙂
Thanks redjr!
These cases (from China (aliexpress.com)) are very solidly and nicely made, I just bought one the same size but half-height for a pre-amp.

Yes, those enclosures are by far the most popular on eBay and in Asia I think. I must have 2 dozen of them in all sizes and variations. I have an eBay supplier that I've worked with for over 4 years now and he carries a wide selection. You can find his store here. Shipping is a little steep, but he packs very well, and will ship most heavy items DHL if you ask - for a reasonable amount considering world-wide shipping costs. Plus they come quickly! 🙂

I see he also sells toroid transformers; any good experience with them?
They are cheaper than what I paid (Avel brand name).
I've never tried his toroidals, only his small R-core xformers that all worked as expected. Since you're in NYC, I've had great experience with Antek in NJ. Right across the river. If what you need is in stock, I think the prices are fair. They are well-made too, and shipping is flat USPS Priority postage.

Here is my LM3886 12,5W audio amplifier. 🙂
