Then big gun contest stations will be the only ones using tube amps. Market gets smaller, prices go up, the fat lady starts tuning up. You're out numbered. On 6/4/2017 8:58 AM, Steve London wrote: I

N2IC and W8HW have made compelling arguments for not viewing this new amp as a panacea, and in pointing out shortcomings that have long been well known. I currently own three Ten Tec 425s, two 87As,

Having built a W6PQL two pallet (2XBLF188XR), I do have some concerns regarding the RF-KIT amp. I have an older (1 yr ago) kit and I flow soldered each of the BLF188's to individual 3" X 5.5" X 0.5"

All fine and good but where on God's green earth did you get $8K? The SPE 2K is $8K but were not talking about that amp (^^^subject line^^^). We're talking about the German amp kit which sells for a

Sorry for the confusion. I was thinking of a pair for So2r. Each kit is over $3K - not including delivery or local parts sourcing. Call it $4K as a round number. And you need 2 of them for a serious

And you need 2 of them for a serious So2r setup Its pretty simple to switch one amp between the radios, so thats not necessarily true. But the amp must be able to run pretty much key down for the who

For me, especially with RTTY contesting, the capability of running this amp on a So2r basis should not be assumed to be workable until it's actually proved. This gets back to my main point. The gee-w
