Model T O)) 150W tube amp kit

0)) Model T - one of the most legendary Stoner / Doom amps of all time. Suitable for both guitar and bass. Model T has lots of strength and power, and the low end is huge. 

The preamp is a version of the JTM45, the power amp uses 4x 6550 / KT88 tubes (also EL34 and 6L6 can be used) to produce 150W without any problem.

The sound is unique and very powerful. 

Please note that the later Model T versions and also Fender re-issues are totally different amps.

• Very high-quality parts, including NOS USA PIO capacitors in the power stage

Transformers

Mains transformer are manufactured in Europe and are massive. The output transformer is from Canada and capable of 20 - 20,000Hz and can deliver all the power from 6550 quads to speakers without any additional compression or low-end distortion, which means it does not limit the massive bass reproduction at all. The mains transformer provides the necessary energy to the amp without any difficulty.

There are two chokes, as in the original.

What does the kit include?

The kit contains all the necessary parts to assemble a working amplifier, EXCLUDING the power tubes.

The builder can choose the model he wants. We recommend 6550 tubes, but KT88 also works, and EL34 (power drops). 6L6GC can also be used, but the voltage is slightly higher than recommended for this type of tube, so only high-quality tubes can withstand it.

Difficulty level

The amplifier is relatively easy to assemble, thanks to the well-designed boards.

The voltages inside the amp are over 500V, so you have to remember to be very careful when measuring and testing. Suitable for a builder who knows how to be meticulous and has the patience to check his work for errors carefully and slowly.
