been in the lab making a new minifenk today.and first had to fashion a special support ring to fit under the oversize top panel pilot lite hole.  so as to capture a magnifier glass up there. so as then looking into the spooky innards of said minifenk and bask in the golden LED glow becomes actually quite trip inducing. these  friendly little guys will always playback your sounds most truthfully tho. flat response dc to daylight and very open clearness from the simple best quality honest transistor amplifier.
