As in the subject line, it is an LTV G133F HF Receiver, and I know from what I have learned about it, that it is a modified Collins 51S-1. A friend sent it home with me because it would not do anything; this friend is not technical. I am helping him with some of his receivers; and, no, I don't charge any money for helping people. The radio has had previous work done on it, but it basically looks OK. Also, I don't have any Collins receivers in my collection ( except for my R-1247/GRC-129 ) so working on this radio will be new to me. This is why I need your help!! I powered it up a few nights ago, and I got WWV on 10 MHz with a three-foot antenna, but that is all I got. The only other thing that I received was a lot of noise. I used the 600 ohm output which is all that I think that the radio has after all of the mods. I found the G133F information on BAMA and I will be using that also. I thought this radio would receive BC band, but I had no luck with that. Here is my main question: Should I put some DeoxIT on the turret ball contacts? By the way, these contacts look exactly like those balls on the underside of some of our modern BGA integrated circuits!! I have some of the red liquid DeoxIT in a bottle that can dispense tiny drops. Here is what I thought about doing: put a drop on the ball contact and then turn the turret slowly 1/4 of a turn ( 90 degrees ), and then the same 1/4 of a turn back. Then do the remaining 3/4's of the turret. This procedure will take quite a bit of time because there are a lot of these turrets, but I don't think that these turrets should be over-lubricated. What do you all do with these Collins turrets, and do they need to be cleaned every several years? This radio has 1829 indicator lamps; it this some special pilot lamp or can I use a 47 pilot lamp for replacement? For some reason the lamps don't work, but they look OK. This is my next anomaly to solve. Many, many thanks for your-all's help!! Everybody have a great rest of the weekend!!

B) They cannot handle QRO power levels in AM operation. 1 KW of AM is equivalent to 4 KW PEP, which I'm not sure the W2AU is rated for.

DO NOT tie the tap outputs together - you could end up with a dead short on your 220v!! I suppose you could stick in a switch to select tap 1 or tap 2 and then start on #1 up to 110v and then switch over to #2 at that point. I think you'd be better off with using a couple of isolation transformers as a 110v to 220v step up. Depending on how much juice you need to provide to the p/s, if you don't have isolation xfmrs, you can use three filament xfmrs to make a 110v to 6.3v to 220v rig for example Nick K4NYW ----- Original Message ----- From: "RICHARD SOLOMON" To: "Old Tube Radios" Sent: Sunday, March 08, 2009 7:29 PM Subject: RE: bringing up ps Use two variacs in series. 73, Dick, W1KSZ > From: bkemp@bobkemp.com > To: boatanchors@theporch.com > Subject: bringing up ps > Date: Sun, 8 Mar 2009 18:25:37 -0500 > > I have to bring up a p/s wired for 220.

I have not before seen such a variety of ways of connecting Variacs, etc. If you have but one Variac and either an isolation (1:1 ratio) trans- former or two hefty filament transformers to use as an insolation trans- former, you might try this method. Bring the ps up from 0 V to 110 V on the Variac alone. After satisfying yourself about the goodness of the ps at 110 V, turn off the Variac and disconnect it from the ps. Connect Variac output in series with the isolation transformer and test across series connected outputs to establish if voltage rises from 110 V to 220 V as Variac is advanced (desired) or drops back toward 0 V (not desired). The latter can be corrected by reversing leads from the iso- lation transformer. Good luck and keep one hand in your pocket.

The latter can be corrected by reversing leads from the iso- > lation transformer. To clarify this, connect the PRIMARY of the 1:1 isolation transformer between the variac rotor and common (neutral). Connect the SECONDARY of the 1:1 isolation tranformer **phase aiding** in series with the variac rotor and the input to the load. Connect the load's return input to common (neutral). In other words, the output of the isolation transformer is stacked on top of the output from the variac. If one winding of the isolation tranformer is connected in **phase opposition** the output voltage will remain at zero volts regardless of the position of the variac's rotor (Rhett got it wrong).
