Customer Question

How can I add the XL function (as on the 333XL) to my old (1/10 build) 333? Can't be too tough.

Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.
Both are 120 W 3-channel tube amplifiers.
explains the four differences, and what the 333XL has that the 333 does not have. The XL function is not well-defined there, but doubtless amounts to an added module.
But there is no such upgrade listed as existent nor offered, that I can find. To upgrade, you might have to take a part out of a 333XL and put it into your 333. That's the only answer I can find, though I am aware it will be disappointing.
If you wish me to look into any specifics, let me know what specifics you have in mind.
