12 RTS100 100 Watt Amplifier PCBs for Sale

[AAK]

Hi Everybody,

I have 12 RTS100 PCBs for sale for $12.50 each. I also have several power supply caps 12000uf/63V (2 per board 35mm diameter) and the output relay for sale for those interested. I'm selling the caps and relay for $2.50 each.

I also have two RTS100 amplifiers completely assembled and tested for $150.00 ($75.00 each) heat sinks included.

The amplifier easily drives 100 watts into 8 ohms and about 185 watts into 4 with the on-board power supply 12000uf per rail. Short circuit protection, and DC speaker protection is also on-board. The amp requires a 35VAC-0-35VAC transformer rated at 250VA or greater for full output.

Here's the thread I started several years ago that describes the amp in more detail. The design is very rugged and reliable and sounds great with better than 0.01% THD mainly 2HD, and 3HD at 1Khz at full power. The prices do not include shipping.

My first solid state amp

Ok, I'll go $12.50 a board with a shipping included. Same thing with the assembled and tested amplifiers, $75.00 each shipping included.

Keep in mind the amplifier has the Power Supply including the Rectifiers, DC, Short Circuit, and Thermal Protection on a single board. It's an all in one solution, just connect the transformer and it's ready to go.

For two boards $25 shipment to Belgium included?

[AAK]

Hi Patrick,

The shipping included was for the US.

Shipping US to Belgium is $13.25 via USPS. How about I drop the price of the boards to $10.00 each and you cover shipping and Paypal fee. How does that sound?

About how much are we speaking?

[AAK]

Patrick,

Comes out to $34.91. That includes the following

2 boards = $10.00 x 2 = $20.00
Shipping USPS US to Belgium = $13.25
Paypal Fee = 3.9% + 0.3 = $1.66
Total = $34.91

Al,
Gonna think it over,I already have a lot of stuff that need to be finished.

I'm dropping the price of my tested and completed RTS100 100 watt amps to $65.00 each including the heatsink. That's $130.00 for both amps not including shipping. In the states shipping will be about $20.00.

The amp features 4.7uf Auricap input caps, two 12,000uf/63V 105C Panasonic power supply caps per amp, Vishay high quality metal film resistors throughout, short circuit protection, DC speaker protection, and an optional thermal protection input.

The only reason why I'm selling these amps is because I need funds to complete several projects that I'd like to publish on DiyAudio in the coming weeks.

It's a great deal for a set of really nice amps. There in all in one solution for significantly less than a dollar a watt. Here's a couple pics of each amp.
