atn ps28 question

[feal]

question for anyone familiar with these things - if the stickers have been removed, how do you tell the difference between the -2 or -3. trying to look at photos online, only differences i can see are on the on/off/remote knob - some are solid, some are notched and some are skeleton.

bump - anybody have a ps28 -2 or -3 that i can compare mine with?

Have you tried contacting ATN?

Yup they recommended comparing it with another or I’d have to take it apart and check out the numbers in the tubes - I’d send it in but they didn’t recommend that right now because they don’t have any tubes in stock so if they broke it it would just sit til they got replacments
