The TriFly is not a toy or a novelty amp! Having 2, full-size 9 pin tubes means interchangeability with both new stock and NOS tubes if you are searching for a special tone. Use the 12AX7 or swap in one of several lower gain preamp tubes or switch from the supplied 12BH7 to 12AU7 for even lower power. A classic power supply is used, not a low cost, unserviceable, switching or charge-pump design now popular in many small amp designs. It is serviceable and generates no radio interference. The point-to-point wiring means you can tweak the tone to your heart's content using classic design techniques and the Red Sparkle enclosure is a dual pedal size that can fit in your kit bag!

TriFly Head Amp


It is an all-tube, one-channel amplifier with Volume control and Power switch and both 4 & 8 ohm outputs. It uses a 12AX7 Preamp tube and a 12BH7 dual Triode high current Power tube, in self-spit push pull mode, running a little "hot" to deliver more symmetrical clipping.
The TriFly uses custom Heyboer transformers and a Conjunctive Filter is incorporated into the output stage to smooth out the overall response.
The eyelet board for the TriFly is a new design approach. Full size tube sockets are located in the middle of the chassis and large access holes through the eyelet board allow easy component connection to the pins. The tubes are aligned so the heater connections are closest making it a very compact and quiet design!

Point-to-point wiring means optimal service and reliability. High-quality tubes, coupling capacitors and resistors are selected for tone, performance and reliability. The Trinity Amps Heyboer power transformer and output transformer are all custom built and designed with maximum tone in mind. The special, large design Output Transformer gives the TriFly an excellent bottom end with a thicker sound and also it has fantastic clean tone at low levels making it sound huge. No other small amp sounds so large‼

What differentiates our kits from others is part quality, fit, documentation and support. This is a full kit with custom Heyboer transformers, tubes and Enclosure. Everything you need to build a working amp. Just add a speaker cabinet or the optional Flip Top 110. Quality parts are supplied such as Switchcraft Jacks; Carling Switches; Belton tube sockets; Carbon Film resistors; Mallory capacitors; 22 gauge General cable hook-up wire; Belden coax cable; Thick 1/8" GP03 eyelet board material. The tube complement is: JJ 12AX7; EH 12BH7. The pre-drilled, Red Sparkle powder coated, die cast aluminum enclosure is only 7.5” X 4.5” footprint and has printed front and rear lettering.
The custom built Heyboer transformer set includes a High VA design Power Transformer and a fat stack M-27 OT with 8 and 4 ohm speaker taps.
We also provide quality full documentation and support and large format 11X17 schematic and colour layout.
You will find that many companies do not supply such quality parts and provide minimum or no documentation. Compare us and you'll find this offering is a great value.
