I get it! Texas Star intentionally manufactured amps with inadequate power cables.

I'm sure you'll get a superior amp from @Ranch55 no doubt. The Toshiba pills alone are superior then the added wire upgrade makes it more sweet.
I was just commenting because you said you couldn't find any available.

You'll have no issues with purchasing from Ranch55. I've dealt with him directly and you'll be hard pressed to find a more honest guy. I have seen his work and it is not only solid, it's impeccably neat and tidy. My piece is still running strong, clean and cool.
As built they work, and in the past they only recommended 20 watts peak drive, but most users often exceed that.
We have to remember that these amps were designed long ago when most radios were single final and really struggled to make 20 watts drive.
They were the best bang for your buck back then for a "out of the box" grey market amp when run as they built them.
They actually got the FCC to give them a pass as a 10 meter CW transmitter ( still think Ed knew someone to get that) I don't think anyone else achieved that.
Now it's the norm for people to think they should take 100 watts of drive and expect 1000 watts peak out of 4x 2879's...
It's a different world today.

Well, the Sweet 16 Qty. available from Ranch likely got slimmer. First lets talk bout the shipping....Good grief they could of airdropped this unit & it would of survived thanks to Ranch's packing! Regarding the unit itself, I am thoroughly impressed w/ the quality of the work & the reports so far are exceedingly complimentary. What a fantastic addition to our collection. I have it married to a Magnum S9. Feeding it 43-45PEP w/ 14.5 V. Output of 1K+ & NO change at all on VSWR! Well worth it. Thank You again Ranch!![image24769[1].jpg](https://www.worldwidedx.com/data/attachments/72/72011-97fb178d5e91b9d93f817d08f5e240e3.jpg?hash=Pp2Ztuxfuo "image24769[1].jpg")

That's a little different. What is the logic of two and four wires in lieu of one black cable and one red cable?
Two wires passes twice the amperage. Four wires passes four times the amperage. With high powered amps the amperage is even more important than voltage.
One 6 gauge wire is not good enough or is it the more strands of wire the better?

On my 500 I have a separate positive wires to each two transistor board to feed them.
On the 8 transistor amps that would be 4 positive feeds, one for each 2 transistor board in the amp.
And the crappy fuse holders get bypassed, directly feeding the amp from the batteries.

Crappy fuse holders are a real curse......... I either bypass them or replace them with heavier holders.
