My vote is to do nothing unless it is really close to intense fields, and if it is....move it about 30 feet. 73 Tom ------------------------------ Message-ID: <4595E95F.4030207@bobkemp.com> Date: Fri, 29 Dec 2006 22:21:51 -0600 From: Bob Kemp MIME-Version: 1.0 To: Old Tube Radios Subject: Noise Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Thanks to all for the help so far on my noise issues: Good grief, I never knew how many household items generated noise.....take a AM radio tuned to 550 kc and start looking around your home!

Flourescent lites It's amazing how many switching power supplies that draw "standby power" are hiding inside consumer products these days. And fluorescent lights can deliver a real surprise, as I found last week while visiting family over the holidays. My mom complained that her 4-tube kitchen fixture was causing interference - to her FM radio! I couldn't believe it, but she was right, nasty buzzing noise covering up weaker stations all the way to 107 mhz. Turns out the ballast had recently been replaced and the ground wire wasn't re-attached. I don't know what's inside the ballast but it's certainly capable of radiating garbage into the VHF range if the ground isn't connected! 73, Bob W9RAN ------------------------------ From: "Ed Sieb" To: Old Tube Radios Cc: "Old Tube Radios" Subject: RE: Speaker Wanted Date: Fri, 29 Dec 2006 23:39:44 -0500 Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Standard stock at Radio Shack.

Cc: Old Tube Radios , n5cm@rtconline.com Content-Type: text/plain; charset="us-ascii" ; format="flowed" Hi Ken, The manual covering the 33 and the upgraded 34 (uses a pair of 6BA6 in place of 6SK7) is on BAMA. Any green on the eye tube at all? If no magnetic pull on the speaker, check for B+ on both sides of field coil. If B+ on both sides and no low ohms short, check why no power draw (need a load to get magnetism). Is output transformer primary open? Is output tube getting voltage at plate and proper voltage at cathode resistor? (Dead tube shows voltage at plate but not cathode.) I repaired a 33 before getting a manual copy. The unit is a dirt-simple dual TRF, detector and audio amp. Suggest replacing all the 0.01 and other wax caps, starting with the coupling cap to the 6K6 input grid. Cheap ceramic caps make good replacements. Nice tool when repairs completed. NRI also made a Conar 230 kit much later. I believe the manual to the 33-34 shows 1947 as date. I'm guessing the 230 to be late 1950's. Its manual is also on BAMA and is an excellent guide to signal tracing. Both the 33/34 and the 230 are fun to play with and use as test gear. Both are decent and sensitive TRF radios all by themselves. The 33/34 covers shortwave also and is in the best tradition of the Rider and Meissner signal tracers as TRF sets. My 33 is pictured at Best wishes es 73, Rich KB8TAD At 3:16 PM +0000 12/29/06, Ken Hickman wrote: > >The signal tracer is "dead" and I am having trouble finding the cause.

Using a couple mercury = wetted relays which do not bounce or chatter, you could arrange your = transmitter turn-on sequence to first disconnect the antenna from the = loop amp and also to short the input of the loop amp, one single-pole = double-throw relay would do that nicely. After that relay has operated, = a second relay could key up your transmitter. The transmitter turn-off = sequence would just reverse the process. The relays operate in well = under a millisecond, so there is no time delay of any substance = introduced even if you are operating CW at any reasonable speed. If you = want a little more information on my differential keyer which could be = used to accomplish that timing sequence, let me know. It's a simple = R-C-transistor circuit.

The probe was open! The previous owner had put a BNC chassis connector for the R.F. probe. The male cable connector had come loose from the inner conductor of probe cable. Now I have a rather loud hum. I haven't checked the two electrolytic yet, a 10 and a 30 mfd in a can. My thanks to Walt, W2OKF, for giving me the address for the manual. I have connected with BAMA but never able to get past the "search". When I entered the name of the unit, I always got "not found". Walt gave me the individual address of that particular manual and it worked. I downloaded the manual OK. My thanks to all who responded to my call for help! HAPPY NEW YEAR TO ALL!
