JE301 Amp Kit - Audio Parts for 60W Dual Mono Amplifier (Part 1 of 4)
Our "à la carte" approach gives you the freedom to design a project that is exclusively yours, unlike standard kits that provide a predetermined collection of items. Just pick what you'll need from the list of four primary components below. (This item is #1 below). In this manner, you only receive - and pay for - just the components you require to realize your vision. If you already have a compatible split rail power supply, or want to use your own rectification circuit, you may skip those items.
JE301 Amp Kit (P/N: 2317775)
Rectifier PSU Parts Kit (P/N: 2796527) - Rectification circuit and power supply wiring components
Metal enclosure. We recommend aluminum for heat sinking. 8"W x 6"D x 4"H minimum recommended for EI-core transformers. See list of compatible enclosures. Toroidal transformers will need a little more room.
Features
Based on Fisher Electronics PA301 Hybrid IC amplifier
This kit contains the audio components for assembling a 60W (30x2) dual mono amplifier
Requires a split-rail power supply providing ±10V to ±30V, (not included)
(for the transformer, we recommend 36 VCT 100VA)
Requires a metal chassis. 8"W x 6"D x 4"H minimum recommended. Should be aluminum for heat sinking.
30 watts x2 on 6 ohm speakers
Clean sound
Direct coupled output for transparent sound
PCB made with silver traces
Gain: 39 dB
Noise: 1.0 mV
THD: 0.3%
BTL (bridge tied load) is possible with additional amp kit and power supply, theoretically doubling the voltage swing and nearly quadrupling the power to a single channel
The Fisher name has a particular place in audio history for those of us who have pleasant memories of the heyday of hi-fi. Although the original Fisher company is no longer in existence, we are thrilled to provide a special project that honors this illustrious brand: the JE301 Dual Mono Amplifier kit, which was inspired by the vintage Fisher PA-301 hybrid integrated circuit.
This is a unique chance to work on a modern do-it-yourself project using historical solid-state circuit architecture. The circuit diagrams and build guide are provided. This project offers a special link between traditional audio engineering and contemporary do-it-yourself skills. This kit offers a fantastic chance to make a piece of audio history with your own hands.
Our à la carte approach gives you the freedom to design a project that is exclusively yours, unlike standard kits that provide a predetermined collection of items. Just pick what you'll need from our list of four primary components. This way, you only receive - and pay for - just the components you require to realize your vision. If you already have a compatible split rail power supply, or want to use your own rectification circuit, you may skip those items. The amp kit contains $160 value of electronics parts.
We recommend the rectification parts kit (P/N: 2796527) because it contains the power supply parts: a chassis-mounted, fused and switched AC receptacle, AC power cord, a 12A 800V full bridge rectifier diode, power LED, extra fuses, hook-up wire (black, white, red, and green), and mounting hardware. Then you choose a transformer and enclosure to complete the amp build.
Skills required:
Solder assembly of components and wire
reading circuit diagrams and schematics
light machining such as drilling holes and nibbling sheet metal
Exercise necessary safety precautions when working with power and mains voltage. Do not touch components while the unit is powered on or plugged in.
