Texas Tone Amps Components selection

Texas Tone 12 Turret Board

Resistors

We use low-noise carbon film, metal film, metal oxide, and/or MIL-Spec resistors, depending upon their function in the circuit.  These are typically 1% or 2% tolerance, don't add noise to you amp, and hold their ratings over time and temperature better than commonly used carbon composition resistors, which are noisy, 10% tolerance, and drift over time. Leo Fender used carbon comp, because that's what he could get in the 1950s and early 1960s.  Resistor technology has improved since then.  We also make generous use of 1-Watt and 2-Watt resistors, rather than the common 1/2-Watt resistors in most amps, for longevity and less noise. 

Capacitors

We use specify high quality capacitors from F&T, JJ Electronic, Sprague, and Vishay, and shy away from generic or no-name capacitors. They're not worth the lower price due to being of low quality. 

Tubes

All new JJ Electronic tubes installed in Texas Tone amps are tested and graded by Eurotubes for low noise and microphonics. 6V6 and 6L6 tubes installed in combo amps have double mica spacers for ruggedness, and we make use of silicone dampers to eliminate rattle and ringing.  The first preamp tube in combo amps is shock mounted.  We prefer JJ Electronic tubes, and these are standard equipment.  New Sensor corporation also makes good Electo-Harmonix and new production Tung-Sol and Mullard tubes, and these are also available.  The Texas Tone 12 makes use of New Old Stock (NOS) GE Electron Tubes for the low frequency oscillator (LFO) and phase splitter. 

Tube Sockets

We have found Belton to be the only tube socket worthy of a Texas Tone amp, and this is what we use. 

Controls

Texas Tone amps feature CTS potentiometers.  We use Alpha pots for the Hypnotic Slam Effect in the Texas Tone 12, due to a lack of availability of the required values in CTS.

Transformers

Due to availability, and the fact that Magnetic Components/Classic Tone Transformers are no longer available, Texas Tone amps feature USA-made Heyboer, Musical Power Supplies, and/or Canada-made Hammond transformers. 

Speakers

Texas Tone Amps is an authorized OEM (original equipment manufacturer) of Jensen speakers, and we feature a variety of Jensens as standard equipment. We also feature speakers by ToneSpeak, and also have available Eminence, Celestion, and Mojotone speakers on some amplifiers. 

Turret Boards

Most of our amps are built on turret boards, made from FR4/G10 Glass epoxy (MIL-I-24768/27), using build techniques guided by NASA-STD- 8739.3.  This offers the highest level of vibration and high temperature performance for the long life or your Texas Tone amp.
