A WORD ABOUT THE s6424 CIRCUIT

The s6424 circuit was produced by Valco mfg. Co. in the early 60's.
Valco made amplifiers for many different amp companies including Supro.
This is the very circuit that you will find in the classic Supro Model 24 and 1614T Amplifiers.

(Guitar World, Jan 1991 interview)
"GW: You were using small amps, like Supros. Those aren't very loud.
JP: The first album was done totally with a Supro. It's got a 12-inch speaker. So, with just that, a wah-wah, a boost pedal [a Tonebender by Roger Mayer] and a Telecaster, you've got a great variety of sounds."

This interview should put to rest any claims that Jimmy used a Thunderbolt which had a 15" speaker.

(2) 6973 power tubes.
These tubes offer the ability to produce sparkling cleans sounds but also roll into a wonderful rich harmonic distortion.

(3) 12AX7's
A dedicated pre-amp tube that shares a cathode with the tremolo tube.
A phase inverter and a dedicated tremolo tube.

5Y3 rectifier.

CONTROLS...

2 Channels each with volume and tone.
Each channel has its own distinct voice and can be dialed in to create many different tones.
You can even jump channels with this circuit to combine the two channels. HUGE!!!

Tremolo on channel 2....Tremolo has intensity and speed controls.
It also has an on/off switch and a foot pedal jack for remote on/off.

The Sound
Great Vox like sound for clean chords and picking.
And a great Supro overdrive like you can hear on the 1st Led Zeppelin album.
This amp sounds great with any guitar...Telecaster, Les Paul, Strat or a ES-335.

The Circuit
The WATTS 24 kit was designed to offer all the best of the 6424 circuit and then some.
We converted the circuit into an easy to follow layout using point to point turret board construction.
Using our detailed layout diagrams this kit is as easy to follow as any other on the market.

The Transformers
With the help of Heyboer Transformers we zeroed in on the best sounding and most accurate set of transformers possible for this amp. The power transformer is to spec with the original and produces the same voltages that you will find in an original 6424. The output transformer is extremely accurate in its' tonal qualities but we also added some weight to in order to achieve a slightly bigger sound.

The Cabinets
Our cabinets were designed to follow the original lines of this very cool 60's amplifier and
we added some height and depth to allow for more speaker options.
