[TenTec] Jupiter Suggestions

[Jack Malone]

Jim:
More info on speaker. I finally got mine the way I want it by using  two
Radio Shack Line Transformers. These completely isolate the input.

Hook up as follows Jupiter to C and 4ohm on the first xformer, then C and
1.25 watt from first to second, then C and 8ohm on second, this assumes you
have 8ohm speaker if not use the tap for your speaker impedance.

The reason I used 4ohm tap on first xformer is the TT specs call for 4ohm
output. Now you can ground the C on the second xformer with no problem. This
makes it compatible with everything that I know of.

It works great on my NVA319 speaker that I use with my JRC NRD545DSP
Receiver. This speaker has the option of selecting either speaker 1 or 2.
The JRC545 uses grounded output to the NVA319 and by mounting my 2 xformers
inside the cabinet and feeding the TT to my second speaker input on NVA319
through the xformers and then into the speaker selection switch and it's 2
hi cut filters & 1 lo cut filter everything works great.
The NRD545 is on a very long wire antenna and this setup allows me to switch
between the TT & 545 when I get a very weak station that I cannot copy on
the TT.
