Friend, Male, 47
I'd like to send it in for an upgrade when it arrives.
Stratus #11 is up for sale and a choke upgrade is mentioned. Are there any other upgrades that have been made to this model?
Yes, I released an upgrade around 2 years ago, changing caps, resistors, and revised the audio grounding. These updates can be incorporated into any Stratus.
