Late 60’s National GA920P 20 watt guitar amp head. Very used but in remarkable shape for its age. The pots are all slightly scratchy and could use a good cleaning or replaced. Originally these came with a small 6 ohm cabinet but this one doesn’t have it. To try it out I used an 8 ohm Charvel CH200R speaker fastened with small test lead clips. Not sure of the speaker wattage, maybe 25? See the YouTube video for a brief demo to show all controls work. Cool little solid state amp from the past. Look closely at the photos, video and ask any questions before buying. Shipping to the lower 48 only an please allow time because of the pandemic.
