I Sale one of my 4 incredibles AKAI ROBERTS M8 from 1964
Amp and preamp moded by professional
technician and casing made by cabinet maker .
110/220V
You can use it like amp head Full tubes with EF86/ ECC83/ 6x4 full-wave rectifier and EL84
like VOX sounds
1 mod: EQ for Low cut frequency variable to have more head room great sounds into my VOX 2X12 Creamback cabinet .. Clean to gorgeous Overdrive
2 mod: Input dynamic microphone For Singer to have best Full tubes crunch and more ....I used it for drums session to have gorgeous rock'n roll sounds and with Synthesizer etc etc....
of course if you use it only with the preamp there is direct Output before EL84 to your Mixer or your Audio digital interface to have Vintage really 60es sounds ..;
The signal is very very clean without any rumble when you play with a fuzz FX when you stop the strings with your hand you can heard the silence ...really incredible ...M8 are created for tape recorder in 60es Roberts was a genius
ask for any questions
In a few times I will make a video with guitar and voice
cheers
