• The F-5 Turbo, an F-5 on steroids, with outputs up to 100w per channel
• The gain stage board can be snapped in half to build monoblocks
• With this kit you can make a 2 channel amp, or a massive monoblock depending on the output desired, PSU voltage, and the heatsinking available! Either way it should be used with the 5U x 400 chassis. You could also make a smaller monoblock using the 4U x 300 chassis, and only 2 of the output boards.

Burning Amplifier Complementary Output Board pair, one for each of 2 channels, with no components, These are designed for the Burning Amp BA-2 which is a complementary design. Usually people order these if they want the 6 output devices per channel with the Burning Amplifier Complementary PCB Set (P-BAC-S4V20). They are also useful to simplify building output stages of other complementary designs.

Softstart - Every time you switch on your monster (or not so monster) power amplifier, the initial current drawn from the mains can be many times that of full power. This is more commonly known as inrush current, caused primarily by huge power transformer switch on currents and empty capacitor banks. At power on, the filter capacitors in your power supply are completely discharged, and acts as a short circuit for a brief period of time until a certain amount of voltage has been reached. This brief period of time can be very harmful to your Power Switch, Fuse, Power Transformer, Rectifiers and Filter Capacitors. This Softstart project is employed to limit these destructive inrush currents by momentarily introducing a resistance between the power transformer’s primary winding and the mains supply, which, after a brief moment, is completely connected to the mains. This momentary delay is already enough to charge the filter caps and limit the inrush current draw.

If you have any questions please visit the Power Supply Soft Start thread thread in the store support forum.

Speaker Turn-On Delay and DC Protector Board - Protect your precious speakers from power amplifier turn-on and turn-off transients and amplifier faults such as DC voltage presence at the output. The Speaker Protector connects your speaker after a few seconds from powering on your amplifier, long enough for the power amp to settle down thus eliminating any nasty thumps that you hear on your speakers. It also provides speaker cut-off in the event there’s DC voltage present in your amp’s output protecting your speaker’s voice coil from burning out.

If you have any questions please visit the Speaker Turn-On Delay and DC Protector thread in the store support forum.

Burning Amplifier Single-Ended Output Board pair with no components, one for each of 2 channels.These are designed for the Burning Amp BA-1 which is a single ended design. Usually people order these if they want more than the 6 output devices per channel with the Burning Amplifier Single Ended PCB Set (P-BAS-S4V20). They are also useful to simplify building output stages of other single-ended designs.

• This is not a beginners project
• These boards have now been proven to work, however we are only currently releasing a limited number to the community until we get more positive feedback.  Consider them beta boards and purchase and build at your own risk until further notice.

This pair of F-4 Clone Boards use the same circuit as the First Watt F-4 model.

It sounds very good, and is extremely versatile, as each channel can be used separately, or a stereo amp can be run balanced for high power. The Amp has no voltage gain so works best when paired with an active preamp that has reasonable gain. Populate these boards with your own components, then add your own power supply, chassis and heat sinks to complete the amplifier. These generously sized, high quality boards spread the six output MOSFETS for efficient cooling. The mounting hole spacing is the same as all other diyAudio Version 2 boards.

The 4U Deluxe Amplifier Chassis makes a great home for this amplifier, and has pre-tapped holes that match the circuit board and transistor mounting positions.

This is a variation of the First Watt F-5 clone with a total of four output devices and a cascode for the JFET input pair, as designed by our member "cviller". The additional output MOSFETS will allow the amp to drive lower impedences better and if you also implement the cascode, jack up the voltage, and have bigger heat sinks- produce more power. We call it the F-5c. If you aren't planning to have a total of 4 output devices and/or cascode the input, then you should probably order the regular F-5 boards here.

Burning Amplifier Gain Stage Board which handles voltage gain for two channels when you populate it with your components. This board is required for both the single-ended BA-1 amp and the complementary BA-2 amp. 

BAGS is the Burning Amplifier Gain Stage board. Being the Front-End, this is where all the signal voltage gain of a Burning Amp comes from. It's main purpose is to provide adequate gain to drive the suceeding output stage of a Burning Amp assembly.

Two Green ACA Printed Circuit Boards with gold plated traces for those who want to find all the parts themselves. Mounting holes fit the Universal Mounting Standard. You don't need these if you're buying the component and PCB kit - they are already included in it.

The PSU (Power Supply Unit) Cap-Diode Board is a universal power supply board suitable for use in most power amp projects in the diyAudio Store. It has been designed to allow CRC filtering recommended for FirstWatt and Burning Amp projects but can also be configured as a capacitor bank by placing jumpers in place of the CRC resistors. An R-C snubber circuit and load resistor is also provided separately per rail and a dual discrete rectifier board section. The rectifiers can accept either TO-3P/TO-247 “Big” diode packages or TO-220 diode packages. Onboard LEDs also provides a visual confirmation when the power supply is powered up.

The diode sections are pre-scored and can be easily snapped off.

• Accepts 4x35mm caps, 8x30mm caps or 8x25mm caps
• Suitable for up to 15 amps
• 1.6mm holes for transformer leads

19 Volt "Laptop Style" Power Supply.  Works with Amp Camp Amp.

One will power two channels, but if you're making separate monoblocks then 2 power supplies make more sense, and it's hard to resist "Dual Power Supplies" in any case!

• 19 Volt Power Supply
• Input: 100-240V ~ 1.6A
• Output: 19V ~ 4.74A
• Standard 2.5mm Female DC Jack

The first Class AB power amplifier to be featured at the diyAudio Store. It has been designed from the ground up with the sonic character, power output and most of all the DIYer in mind. With a basic power output of 150W at 8 ohms, this power amp is sure to have a place in every builder’s projects list. Not to mention its flexibility and adaptability to work with most output devices available locally in wherever country you may be.
