Re: [Drakelist] AC-4 Load Bank
hi folks, Some yrs ago there was an article on building a test setup for Collins p.s.'s. I think it was in one of the Collins collector magazines, I can search it out. I came into possession of one of the units, and have made cable adapters for the AC-3/4's, and I think the HP-23's also. It is for voltage only, and did not include a load test, but I have been thinking of adding that to mine. 73, Al, W8UT www.boatanchors.org www.hammarlund.info "There is nothing -- absolutely nothing -- half so much worth doing as simply messing about in boats" Ratty, to Mole On 11/26/2012 11:30 AM, Hudson, John@CalEMA wrote: That would be a useful test jig.

Re: [Drakelist] T-4X RF Tune Vernier?
Thanks Gary. I had suspected that when I inspected the chassis bore for the RF Tune shaft. I has no discoloration or friction marks to indicate that a vernier was ever stripped out. I had thought about scrounging a vernier and knob set from a junker T-4X, but now I think I will keep it authentic. Looks like we have the same vintage R-4A. 73 - Luke - K6LO On Nov 26, 2012, at 5:46 AM, Gary Winblad wrote: > Nobody touched this one. > Yes Luke, there are early and later T-4X's. > Like you, I have an early one without vernier.

Re: [Drakelist] T-4X RF Tune Vernier?
Nobody touched this one. Yes Luke, there are early and later T-4X's. Like you, I have an early one without vernier. It also has 5khz marks on the main dial. Later T-4X's get the vernier and only 25KHz marks. My R-4A is mid-production and has 25KHz marks and vernier but is the earlier 13 tube version. Years ago I had an early R-4A with no vernier but with 5KHz marks. 73, Gary WB6OGD - Original Message - From: Luke Rainville To: drakelist@zerobeat.net Sent: Wed, 21 Nov 2012 15:28:45 - (UTC) Subject: [Drakelist] T-4X RF Tune Vernier? Were there two versions of the T-4X? Mine has a straight through RF Tune shaft, indeed the manual cover shows a T-4X with a bar knob like mine. However I have seen T-4X's with R-4A style red pointer vernier RF Tune controls.
