Hello! Thanks for checking out the AMPSAMPS RU-vid channel.
This video features my four watt WT4 amplifier.
The WT4 is a Class A single-ended amp that features a single EL84 in the power section and a 12AX7 preamp. EZ81 rectifier tube. Single volume control, high impedance input, treble/none/bass boost three way way toggle, speaker out.
The inspiration for this amp was the Moviola URS & Ediquip 1027a squawk box amps. The Moviolas are awesome, but not loud enough for me. So I studied the Moviola circuit, as well as the front end of my favorite Valco low-wattage combo amps, increased the voltage and the size of the output transformer, and swapped the 6AQ5 for an EL84.
Housed in an ammo can, I repurposed a Hammond AO-44 reverb amp chassis for this build. I completely gutted and rewired the chassis using quality components and thoughtful lead dress.
This amp is perfect for at home jams and huge sounding recording tones without the large-format volume. Another cool thing about these single-ended amps is the ability to easily try out your entire stash of 12A_7 tubes and EL84s both for function and for tone! Put in a 12AU7 and hook up your iPhone for a classic mono tube audio experience… I have done a number of these over the years, most notably for Joe Cardamone of the Icarus Line.
This hardwired, upcycled, handmade little ripper is a steal at $500! Orders received before 3pm PST ship same day, and as always, my amps come with lifetime warranties to the original owner.
