Conn 73H Bass Trombone

[CamiloJimenezVera]

Hello to all, I have a vintage bass 73H with the second valve in E. What do you think of this instrument?

[BGuttman]

The 73H was a dual valve based on the 70H family. While a bass trombone in Bb/F/Flat E can be useful, it is more common to add an extension to make the second valve in either Eb or D.

The 73H was never as popular as the 62H. If you are looking to sell this for a retirement account, look elsewhere. The asking price for this won't be astronomical.

Absolutely brilliant trombones. I pulled my 2nd valve out to make it nearly Eb! Better in some ways than the Bach 50 I replaced it with, notable reason Bach better, independant valves 2nd to Gb.

Does the 73H slide have springs or corks in it?... Doug

The one I played had springs.

Well, the factory gave them springs. But a lot of folks don't like springs and replace them with cork or felt.

Thank you very much. Not is my interest to sell this horn.

Thank you so much… I fell B low more confortable and in tune with 2d valve in E. I will try to split the triggers.

And if you search eBay, you will see that Taylor Music in SD has *new* D slides for that horn! For $75!

I recently bought one of those D slides on eBay. They are absolutely "new" as advertised, as in "new old stock". Haven't had the chance to start incorporating it yet but after 48 years of playing with an E as my second trigger, I'm looking forward to not having to reach so far out for the low C. I have never played a split valve bass bone but find the triggers on the 73H to be pretty easy to slide your thumb over to press the second one.

Works like a charm. Balance is good. Here is pictures.

The mechanics with strings were replaced on both valves and the result is it's a more modern design. The horn is more usable to "modern" players but there is also one negative aspect and that is it's now a bigger throw on both valves. Strings means less throw and I had pretty good technique on the old side-by-side setup too. This is something one should consider before you split your triggers and keep the old valves. If you also switch to other type of valves such as thayers I suppose the throw is compensated by the modern design of this valve. My descition was to keep the valves to keep as much as possible of the the old Conn sound. There is also a risk with a split that the balance is lost and the new grip makes the horn more difficult to hold. You might not sense the stress right away when you try the horn at the collect in the shop and the result can be you may need to see your tech several times and fine tune. Lars Gerdt made my second valve so I can move the pad around and this was a good thing. I could fine tune at home.
