Mogwai SE Rev 2

Stock: 8 weeks shipping from date of purchase.


The Mogwai combines the features of a full-sized two-channel power amplifier and headphone amplifier in a chassis that is suitable for a desktop use.

The Mogwai utilizes single-ended Class A operation with zero feedback to provide the essence of our Classic Wonder sound; strictly old school SET sound, without having to spend hundreds if not thousands of dollars on tubes.

The performance of the Mogwai is made possible with custom wound ultra-high quality output transformers from Transcendar, which provide excellent frequency extension and a flat response.

The Mogwai does not use a voltage divider network, but depends on transformers instead. We chose a 32 ohm tap for headphones to offer a dedicated selection for the widest range of headphones, and an 8-ohm loudspeaker tap to connect the Mogwai to moderately efficient loudspeakers.

Generation 2!

The close of 2021 has brought out more than 18 months of a global pandemic. During these challenging times, we at ampsandsound strengthened our development efforts resulting in new generation of our classic amps.

Though octal input tubes provide a romantic character that had defined the ampsandound house sound, reminiscent of 1950s HiFi, the downside to this approach is a reduced noise floor and dwindling NOS options. With ampsandound moving to a 9pin front end, performance has been increased, NOS tube rolling has become nearly limitless, and yet we were able to enhance the sweetness and tone we are known for. The 9pin front end allows vastly increased options for tone rolling to find your balance and preference.

With our front end's new development, we have improved our amps further, including both subtle and significant changes alike. Notable takeaways include increased power output, reduced noise floor across all our amps, increased bandwidth.


  • Input tube: 12AX7, ECC83 or equivalent
  • Output tubes: 6L6GC, EL34s, KT66, KT77, KT88, 6550s and KT90s

A personal favorite of the designer is the Tungsol 6L6GC STR. Warm, strong and tight bass. A personal favourite of me, Hugo, are EL34s for their incredible timbre and midrange. Sophia Electric EL34s especially give such solid state renidition - clean and linear but still with all the best bits of EL34 tubes). 

Cathode Bias/automatic bias allows for easy tube changes without adjustment.
Compatible with 32ohm-300ohm headphones using the “32ohm” 1/4″ jack.
