There are several other possibilities. The orifice oring or gland could be bad or (and the thing I would suspect) is a defective/contaminated balance chamber oring (or a scratch in the balance chamber itself)

... The orifice oring or gland could be bad... I was thinking that might be the problem too, but seeing as I have zero idea as to what this mod looks like, I thought I'd stay silent on that subject and wait for either you or Luis to chime in JB

I have my regulator back together again now. I sent the Cyclone in and VDH replaced the volcano orifice and the HP seat. The IP is holding steady now. Thanks for all the input on here. Now I just need to find somewhere to put it in the water to give it a better check. This has been a fun project working on my first double hose regulator.

I put by Cyclone/HPR DA Aqua Master in the water today for the first time. Actually this was my first time using any double hose regulator and the first one I have rebuilt. It worked really great. In total I spent almost 90 minutes in the pool with it. I actually breathes better than the new octo that I have connected via the hookah port. That was a nice bonus surprise. I can't wait to try it in open water. Thanks everyone for your advice on here that helped me get it up and running. I believe my DA AM is from 1960.

If you don't keep a close eye on your DH regulator pretty soon you will have 2, then 4 then 6.... Some form of asexual reproduction I believe.

Everyone on this board knows that you have been sucked into the vortex.
You might only have 1 or 2, now.
But, you will probably be filling crates with them soon. If you are strong, maybe you'll only end up with 10-20.
I am so sorry.

I know have 4 working Snark3's, 4 or 5 on the "to do list", 4 working USD in various states of modification, a DAAM and a RAM in the project box, 2 working New England Divers, a working Sportsways and another in the project box. This doesn't even mention the bins of single hose projects. I have digressed to many vintage tanks too....................

It’s a crazy phenomenon. It hasn’t even been a year and I’m at 5 DHs now…

Now I can officially say I have dived on a vintage double hose regulator. Yesterday I made two dives at Lake Phoenix in southwest Virginia. We only went down to about 25 feet, but my old reg worked like a champ. Not bad for a rookie.

I’m continuing on with this rebuild after it was shelved since the fall.
Anyway, in the crown block all I could remove was a small black o ring. I did not see any backup washer. If there was one, would it be a white part?

Some have a multi part balance chamber (not a crown block) for ease of servicing the o'ring, but the earlier ones are one piece and don't have the teflon washer. The o'ring must be carefully dug out and replaced. Use soft picks, NEVER steel! This process often includes lots of bad language.

yes it was a PITA. I carefully had to break it with steel pick and then plastic to remove. I'll be investing in a brass pick shortly if that's what you'd use for things like that. Can you tell if my crown block is supposed to have a backup washer based on this pic? I didn't think mine was a very early model and was expecting to see one, so I figured whoever serviced it may have forgotten to put one in. But then I remembered that Luis said this one had likely never been serviced...when I put a backup washer and o-ring in, they fit snug inside the block with the oring pretty flush to the end USD RAM crown block by Jim Perdway, on Flickr

If the end is open and the o'ring will slide in, you have the late balance chamber. If the end is closed over the o'ring, and it has to be weaseled out you have an earlier one. The later ones use a backup washer over the o'ring. Check out the diagram here: vintagedoublehose.com/store/#!/UPDATED-Crown-Block-Backup-Washer/p/83228229/category=1964152
