[TowerTalk] Looking for a HP 80/40 Duplexer

[Jack Brindle]

DX Engineering only sells the low power VA6AM devices. Pavel has a very good selection of high power devices that are the best available.

I am a very happy user/owner of a full set of his 2KW filters along with one of his mid-power triplexers that handles my C3S quite well with my KPA500 driving the stack. 
Check his stuff out: https://va6am.com/

I've located sources for most of the up-rated bandpass filters and other hardware required for the project, but can't seem to find a source for a duplexer to split a 80-40 dipole for SO2R use. I'm presently using one of the Low Band Systems 500W 80/40/20 triplexers for this function. LBS apparently makes a 1500W 80/40 duplexer, but it appears the LBS stuff is no longer available in the USA. Does anyone have or know of a suitable 1500W unit? I do NOT need it to be rated for 100% duty cycle since I'm only interested in CW and occasional SSB use, but it needs to hold up under contest conditions with a full power amplifier.
