These are the exact original transistors used in Thomas Vox amps from the 1960s. Most of these transistors are discontinued items and are no longer available. While you can still buy "generic, one size fits all" transistors from substitution suppliers, why not use the correct parts and keep your amp, and it's tone, original? No returns, exchanges, warranties, or exchanges on transistors. All sales are final.
