Thank you for viewing. This is an auction for a GUYATONE GA-100FC, a hybrid amplifier using a 12AX7 in the preamp section! Fully functional!! This model was released in the late 1980s and features two original vintage National 12AX7 vacuum tubes in the preamp section, along with a Celestion G8L-35 8-inch speaker. Controls include GAIN, VOLUME, BASS, MIDDLE, TREBLE, and PRESENCE, with SEND/RETURN/LINE OUT/headphone jacks on the back. Although it's a 10W output, it feels more powerful. Currently, there is no crackling or noise, and it remains a very popular model. ■Maker: GUYATONE ■Model: GA-100FC ■Serial Number: 3210261 ■Size: 338mm x 325mm x 190mm ■Weight: 7.4kg
