Trinity Triwatt Kit
The TRIWATT is based on the classic design originally pioneered by Dave Reeves of HIWATT fame. This new offering has a preamp inspired from the early “4 Hole” and David Gilmour’s of Pink Floyd legend, “3 Hole” versions, where there are two bright channels inputs and a third which links the two channels together for that classic HIWATT sound, reminiscent of The Who, Pink Floyd and many others.
The TRIWATT was designed by Trinity Amps to capture the classic HIWATT sound without the usual classic ear-bleeding volume levels. It is closely based on an early ’70s style HIWATT DR, but utilizing either 6V6 or KT66 power tubes for more usable power output. Furthermore, it has the 3-input configuration used by David Gilmour of Pink Floyd, plus an Overdrive stage, as found in early ’80’s “Biacrown era” HIWATT Lead amps
Key points about the CUSTOM TRIWATT LEAD Design
- Designed with HIWATT tone in mind from the onset
- Preamp based on the late 60s/early 70s style 103 preamp, with the cathode-follower in front of the Phase Inverter
- Three-inputs, for Normal and Bright and Link, as found in Dave Gilmour’s early 70’s 3-input amps
- Second stage can switch between early HIWATT and 80s’ higher gain Lead modes with variable Overdrive control
- Phase Inverter tube can be 12AT7 as in the earlier Hiwatts or 12AX7 for increased drive to the power tubes
- Solid State rectification with fixed bias 22 Watt 6V6 output stage, based closely on the original Hiwatt power amp and power supply
- 6V6 or KT66 operation with External Bias Switch, Bias Control and Test Points

Triwatt Sounds Incredible John B Hunt, Powhatan VA, USA
I wanted to drop you a line to tell you how much I’m enjoying my Triwatt build. I finished building it a couple weekends ago, and have been putting it through its paces daily ever since I first fired it up.
In short, it sounds incredible! It has a LOT of headroom, with punchy cleans, strong mids and treble chime. The bottom end is tight and well defined, and I now understand what you meant about the EQ being “hi-fi” sounding. There are a wide variety of tones to be had by adjusting the EQ knobs. My Triwatt takes pedals like they’re part of the amp, and although it can get VERY loud, it is still quite manageable with the Master Volume. I’m currently running it with KT66s, and it is every bit as loud as my JTM45 build, but the Triwatt holds together better than the JTM45 at extreme volumes. The overdrive circuit is a nice addition, and it adds extra dimension and chime to the high end. At low settings (approximately 9 oclock) it blends unbelievably well with my boost and OD pedals. The linked input is a great feature, as I like the ability to blend the levels of each channel for further tone shaping. The amp sounds equally good with humbuckers and single coils, but I’m really enjoying how much more punch and girth my Stratocasters and Telecasters have through the Triwatt. Almost as if I’d stepped up in string gauge…
I’ll be gigging it at a couple clubs this weekend, and an outdoor festival gig the following weekend. I can’t wait for the opportunity to really open it up and see how it shines on an outdoor stage.
I’d like to thank you for providing such a top quality HiWatt inspired kit, for DIY guys like myself who get almost as much pleasure building amps as playing them. Your customer service and product support are both outstanding, as is your kit design and quality of components. I greatly appreciate all of the effort you’ve put into this amp design and your attention to detail with the kit. Kudos to you, sir! I wish you much continued success with your company.
Thanks again Stephen and have a great weekend

Just wanted to follow up on my Triwatt build, I had no problems whatsoever and it works like a dream! Your description of the amp on the site and in the (extremely well thought out and written) instruction manual is accurate to a T and yet the amp sounds better than I’d have ever imagined. The versatility it offers is incredible and I haven’t even begun experimenting with pedals! If you didn’t offer any other amps that I’m dying to build, this would be my last. It sounds that good to me.
I’m more than willing to review Triwatt on other sites that you prefer as well!
Thanks again for your support, product, and dedication to the customer/ builder.
It was an absolute pleasure working with you and I hope to again in the future!
