Ordering Boards and Hybrids, Completed Amplifier

I will ask the following:

1/ If you Order 1 Dual Device Board, there is no problem, Hybrid's are built in the Boards.

2/ If you Order 2 X Dual Device Boards with the intent of combining these 2 boards, please order 1 X 4 Port RO4003C Hybrid and 1 X 4 Port Taconic HP Hybrid.

3/ If you Order 4 X Dual Device Boards with the intent of combining the 4 Boards into one Amplifier please order 1 X 8 Port RO4003 LP Hybrid and 1 X 8 Port Taconic HP Hybrid.

4/ If you wish to order 8 or 16, or more for a very HP Amplifier please conctact me to discuss needs relative to Hybrids.

The Hybrids I fear will be going up in cost and I suspect the Amplifier Boards as well?????, in either case it becomes very costly to inventory all that may be needed, especially the Taconic Hybrids at $1500, to $1600 an Order.

Presently I have New Order of slightly revised Dual Amplifier Boards, 4 x 8 Port Taconic, 24 X 8 Port LP Hybrids, 7 x Taconic 4 Port Hybrids, 23 x LP 4 Port Hybrids in Stock, The slight revision will allow an applied VDC to Drain change from 26 to 30VDC with 30 less watts in Power Loss.

I am also presently working on a controller Board for the Amplifier, that will allow input level adjustment as well as VSWR Set point at any level input between 0.7V to 3+ V with tripping level of ~0.2V at any level of input.

There will be times I am sure where extra Hybrids may be available, but please ask before ordering beyound your immediate needs. ve1alq(at)nbnet.nb.ca......remove the (at) and insert @
