These board kits can be modified with alternate pre/PI/output tube configurations.  Contact me.

You can choose different brand caps and resistors to have on your kit:

NOW with Jupiter and Mallory tone caps!
Prices have increased due to the cost of Jupiter caps.
But the tone is worth it!






Each garolite insulator board is hand drilled and assembled in eyelet style turrets.
Detailed instructions, mounting hardware, power filter caps,
select kit pots/switches included (varies per kit).
20 AWG stranded wire is now included and attached to their eyelets.  
You cut the excess wire to fit to each tube socket pin.
Solder not included.

Transformers, chokes, tubes and tube sockets are not included with the kits.

Ask me about ordering custom wound Heyboer transformers and chokes to help make your Gibson
clone or to restore your vintage Gibson amp (limited available part numbers).

If there is a different Gibson model board kit not posted here
that you'd like to inquire about please contact me.

Please read my warranty page for warranties and safety warning.  
Warranty service applies to transformers and passive components.
