Can you find a Marshall AVT5o 50w combo channel selector?

Finding a Marshall AVT50 50W combo channel selector may be challenging as it's a specific part for an older amplifier model. You can check online marketplaces like eBay, Reverb, or specialized music gear sites for used or new parts. Additionally, contacting Marshall directly or visiting local music stores that carry vintage gear could provide further options. If you're looking for a replacement, consider guitar forums or community groups, as members often sell or trade parts.
