| TVA30
is loaded with features and breathes life into your sound with a dynamic
responsiveness and character found in the finest of tube amps. It's rich
with tone and versatility, and exciting to play, revisiting decades of legendary
guitar music and bringing you into the current era. You just won't
want to stop playing. Hidden within the relatively straightforward control layout is a range of high quality sounds and a versatility that makes experimenting fun. The tone controls have an interaction and breadth that brings more sound to life than you'd expect from 3 simple controls and a switch! And, there's no need for external overdrive or distortion pedals. The two channels each have their own dynamic for overdrive and distortion that has a feel and response you find in the finest of great amps. And, an important part of the TVA30's versatility is that you can play at low volumes and achieve wonderful sounds - thick and rich, even with heavy distortion. A wonderful sounding reverb is another hidden treat in the TVA30; custom-designed to fit our sound ideal. It fills out the sound without springiness, a metallic edge or ringing; it adds believable depth without changing your sound. It sounds like - reverb - not like springs in a can. TVA30 is more in the class of boutique or high-end amplifiers, considering its build quality and performance, though it is priced more affordably. We're using higher quality components and construction, though much more expensive, to provide greater reliability, more stable operating characteristics and a substantially higher quality of sound. Some of the most critical components, such as the transformers, speaker and reverb tank, have been custom-designed and manufactured specifically for our TVA30 in order to achieve the performance and sound quality we desired. While it is a more costly approach, the signal paths of the two channels are completely separated and disconnected from each other by electromechanical relay switches to eliminate any interaction between the circuits which would compromise performance. The attention to detail and commitment to reliability and performance over cost and efficiency have made the TVA30 about 80% more costly for parts, materials and production than you would find in standard amplifiers of this type. But, there is simply no way to have low cost and achieve performance and reliability, even with economies of scale. We have not comprised integrity to the principals in order to minimize cost. This is not a budget, "good for the money" amplifier. The TVA30 is an amplifier designed and manufactured for world-class professional performance and recording. |

We use ceramic
tube sockets for greater reliability over time. Dependable, Highly Reliable, Low Noise, Boutique Class, High Performance Tube Amp Construction Point-to-Point
Hand Wired construction
and PC boards
are used for greatest reliability. No connectors or multi-pin connectors
are used inside the amp except for RCA connectors to the reverb tank.
Everything is hardwired for reliability, lower noise and better conductivity.
This is a much more expensive way to build an amplifier; so much hand
labor is involved. But, the consistent performance, long-term reliability
and low noise depend upon it. |

Shielded
wire is
used extensively for all critical signal paths. You won't find this in
most amps. It costs a lot more and it adds a lot of labor, but it reduces
noise so dramatically it is completely worth it. But wait, there's more.
The shield of every shielded wire is only connected at one end. That way
it shields the signal path without creating any internal ground loops,
again reducing hum and noise. All of this tedious attention to detail
adds up in the total performance, quality and reliability of the
TVA30.
Notice how neat and clean the whole assembly is. Loose wires can create varying noises in an amplifier. The high-end, hi-fi construction and workmanship of the TVA30 is evident in its performance. |

| Signal Path
& Components The Output Transformer ... a critical link in performance Here is the typical size of a 30 watt output transformer as you will see employed in many amplifiers of the 25 to 40 watt power range (including many "high-end" models). Beside it is our custom-made 70% overrated output transformer. It costs 7 times more than the conventional transformer but the difference in sound quality, reliability and performance is huge! Try this amp with a bass through a good bass cabinet and you'll realize the low frequency performance! You can deliver clean strong lows without breaking up, and heavy distortion that won't get thin, mushy or gritty. You're sound can maintain its punch and clarity, even at high volumes. Those small transformers are like trying to put out a fire with a garden hose. The TVA30 transformer is a fire hose! |

Toroidal
Power Transformer "If you want serious performance from your tube guitar amp, it takes smart circuit design, components and construction like this to achieve it." |
||||||||||||||||||
| Class
A Power Amp - 4 EL84/6BQ5 power tubes in a high voltage
Class A (adjustable) DC bias grounded cathode design for greater stability
and better performance under dynamic and high demand conditions. It's Quiet! Low hum and noise. A single point chassis ground is employed and internal shielded leads are drained at only one end to help eliminate internal ground loops. There are no connectors in the signal path to add noise or static and high quality capacitors are used to minimize component generated noise. And remember, the toroidal power transformer reduces hum and noise, too. Reverb - It's custom made with 3 springs of different time constants and envelope characteristics. The drive and recovery circuits are equalized and tailored to control the attack envelope and overall timber. The reverb has a full response and a decay taper that isn't too long, but also not too short. It feels natural and realistic. |

Effects
Send/Return Plus! The Effects Send can be used as a Preamp Out or Direct Out without breaking the signal flow through the amp. Plugging into the Effects Return jack breaks the signal flow through the amp and can be used as a Power Amp In. The Return has a level control for matching effects levels or setting power amp input levels. The Effect Level Control is not active until a mono ¼" plug is inserted into the Effects Return Jack. You can even use the Effects Loop to make the TVA30 into a Master Volume amp! |

| We
believe you'll find the TVA30 to be a joy to play, adding
to your range of expression and tonal palate. We've worked hard to help
insure reliable, long-term performance. As
with our guitars, our goal remains to help you Play Better
and Sound Better.
