Trinity Project Boards

We offer our Trinity built boards for your DIY project. These are the same boards we use in our completed amplifiers. These boards use turrets.

Tone Tubby Ceramic 10″ speaker with the standard H1E Hempcone has the same voice coil and similar magnet as the Ceramic 12″. So this is a BIG sounding speaker in a small 10″ package! The Tone Tubby Ceramic 10 offers an amazing range of tone, throughout the entire guitar frequency range.

10″ Tone Tubby Alnico

The Tone Tubby alnico 10 offers an amazing range of tone, in the guitar frequency range. More overall lows, mids and highs, with NO “cone cry” or “ice pick highs”. A smooth and warm tone, with a mid-range airiness and fat, silky and thick overdrive.

12″ Tone Tubby Ceramic

Tone Tubby Ceramic 12 speaker, with the standard H1E Hempcone offers an amazing range of tone, in the guitar frequency range. More overall lows, mids and highs, with NO “cone cry” or “ice pick highs”. Classic ceramic magnet speaker clarity and definition, with later breakup and more clean headroom than its alnico counterpart.

12″ Tone Tubby Alnico

The Flagship Tone Tubby AlNiCo 12 offers an amazing range of tone, in the guitar frequency range. More overall lows, mids and highs, with NO “cone cry” or “ice pick highs”. A smooth and warm tone, with a mid-range airiness and fat, silky and thick overdrive without any harsh high end. In a recommended open back cabinet, the mid-range airiness provides the most 3-dimensional tone, when compared to the other speakers.

Voltage Regulation Module (VRM)

The VRM (Voltage Regulation Module) is designed to control the power level of your Cathode Biased amp while retaining the tone. The 1″ sq. board should fit anywhere in your Trinity Amp with three simple connections. Replace the power switch in your amp using the “switched” control pot.

Trinity Tweed Kit

Trinity Trip Top Amp

Based on several years of vintage Ampeg B15 designs, the Trip Top combines the original circuits of both the Ampeg B-15NC (1964) as well as the later B-15NF (1965-67). The B-15-NF channel has the volume control section before the tone stack and in the B-15-NC channel it is after. Maintaining these circuits keeps the same gain structure and biasing found in the original B-15N amp designs, helping to preserve their true heritage.

Trinity OSD Amp

The heritage of the Trinity Amps OSD (Overdrive Special Design) is a Dumble Skyliner concept in a compact format with slightly fewer frills. These amplifiers are synonymous with the rarest finest boutique amplifiers used by Stevie Ray Vaughn, Eric Johnson, Carlos Santana, John Mayer, Robben Ford, Larry Carlton and more.
