5th Valve Addition TU330CC
Posted: Mon May 08, 2017 10:07 pm
Has anyone had a 5th valve added to a Holton TU330CC? If so, who did the modification and where are they located?
Here's a few pictures of the horn:
Front View
Tuning Slide Knuckle out of 4th Valve
Tuning Slide up to Bugle
Lead pipe into 1st Valve
Main Crook 45 bend out to Bugle
Back of Horn View
All slides are currently frozen, so all measurements were taken with a micrometer on the outside surfaces:
Lead pipe .660"
Knuckle out of 4th valve .743"
Outer tuning slide from 4th valve .773"
Inner tuning slide from 4th valve .732"
Inner tuning slide to bugle .798"
Outer tuning slide to bugle .844"
Main tube to bugle .804"
Thank you all,
