just spent some time poring over the schematics on the apeks regs from seaquest. it appears that there are basically only 2 second stages in the range if you ignore the different faceplates. both are balanced, both have the venturi adjust but one is adjustable for cracking effort, the other is not. all internal components are identical except for the adjusting knob and one oring. if you want the basic non-environmentally sealed first stage with no swivel (my choice) but want the adjustable 2nd all you have to do is buy the T20 (non-adjustable 2nd)and then add the adjusting knob with its o ring in place of the blanking plug it comes with. unfortunately seaquest will not mix and match 1st and 2nd stages as george ointed out but this is an easy way to get the combination desired. also seaquest will not sell it as din only - it's necessary to buy with a yoke fitting and add the din adaptor. the part numbers from seaquest to convert the 2nd are AP1409 oring AP2029 adjusting screw If you want the little decorative plug for the end of the adjusting screw it's # AP2030 hope this helps Tony Phillips ----- Original Message ----- From: Richard Lister <ric@gi*.ge*.ed*> To: <trey@ne*.co*> Cc: <divewrecks@ho*.co*>; <techdiver@aquanaut.com> Sent: Friday, May 26, 2000 3:48 PM Subject: Re: Trey - Apeks Reg Question > On Thu, 25 May 2000 05:59:30 -0400 > trey@ne*.co* (Trey) > wrote concerning 'Re: Trey - Apeks Reg Question': > > Apeks calls it the US 4 .I use the non adjustable second for backup, and > > either that or the adjustable for primary and stages.
