A way to see some of the gear I have for sale

As of late I have been keeping a fairly current list of gear for sale on the local Portland, Oregon Craig’s list. Just go to Portland’s Craig’s list and the electronics for sale category. Type in the search for Classic Tube Audio and you will find me, my ad is mostly current and has items that are expected to come in  soon “New Arrivals”


If the link here is dead as the ad renews each month just follow the instructions above


Thanks Dr. Tubeology
