Yeah, that is a bridge rectifier solid state swap in, same if you did it yourself with diodes. and it would remove the possibility that all your 12bw4 tubes are bad since you said that they didn't test too well.

no one sells a tube kit, you will have to piece meal it all together. Boatanchor restoration is not cheap, I usually find myself spending a couple hundred dollars per rig I am restoring so that is why I only have super clean rigs.

I own three businesses so my time on the radio (or this computer) can be limited and sparse at times (no daily routine like most people) so I was only trying to talk to other am high fidelity operators on the superbowl who also had modified receivers like my kenwood which was very wide banded...

The only power adjustment is C49 plate tuning, and there is no mic gain or such control so you would need to replace resistor(s) with different values like I had on my tram (my tram was too loud), or get a desk mic like a D104 or similar with a built in preamp/volume control so you can use that...

I operate MURS everyday, MURS is nothing but VHF CB, gets out like 2meters does, might actually be a touch better. My 5 watt handheld gets out 8-10+ miles with a 5/8 wave full blown telescoping antenna on it.. There are base stations at the fringe of my receive about 35 miles away, I can hear...

I bought all my 100uf/450vdc tube radio power supply restoration caps from mouser. They were like $2.46 each. You will have a harder time finding axial capacitors and if you do they will be too much money, just use radial and bend the leads, fit it in and make it work...

Hell yeah its all for fun. anything is better than nothing. I have used a w2ihy 2 band eq to various 31 bands, the more bands, the better ultimate voice control. For the 31 band,I did it a couple ways, once with a modified Behringer DEQ-2496, and the other with the Digi Designs Mbox series...

I have heard a Icom 746 (non-pro) on AM a couple of times (these were on 40meters and 6 meters) and it sounded great. I like the fact the 746 has 2 meters built in at 100w output.

Here is how I achieved great AM audio on 11m using a ham radio consisted of the following setup (This was back in 2007-2008): ~Kenwood TS-850SAT (balanced modulator input mod) I bought this radio from ghettoway driver from southern cali ~Blue Kiwi Microphone ($1,999 retail) (I tried over 20...

SDR-1000 rare? In the past two weeks, I have seen 3 listed, all 100w models. One was $500 and the other was $700 with 2m transverter, that ad has since been deleted. In fact a 100w SDR-1000 was JUST listed yesterday! $499! (I dont know how long this link will last given if it sells on the...

FYI, Not exactly for the SDR-1000, on this forum you can download the unlocked software which is unlocked for 11m, follow this thread, http://www.worldwidedx.com/threads/flexradio-mods-a-wwrf-first.69366/ but for all the other newer FLEX radios yes you need to send them your mars certification...

New radio? TS480SAT or HX. On the HX, I read they can be setup to key 40-50 watts and swing to 200 watts on AM and have high level style of forward modulation, one guy said they can sound like a plate modulated radio, so take it what its worth. I have never used or heard one but this is what I...

One thing I never got a chance to getting around too back in 2009 before I took every thing down and moved, was inquiring with Andrews or Commscope if they could make a custom length of hardline made with complete pure silver conductors (not silver plated!) instead of copper (or atleast the...

Yes, negative side goes to ground. The positive side goes to rectifier tube output, it should be very clear in front of you.

I did a number of test on vhf/uhf with LDF4-50A (half inch)and I noticed a improvement for sure over the LMR400, I cant exactly remember the improvements but they were more substantial that the much smaller improvements I seen at CB freqs. This was all done over 10 years ago. I was running a...

you guys are only seeing and talking about "half" the picture here (TX), its totally not about the power number "specs" here like 86 to 97 for example, when in reality it is about sensitivity from outside antenna signals getting from the air to your receiver. It needs to travel through your...

ok your good to go with that cap you got, put it in. I don't know about the paper cap your referring too, I have never seen it in person, but if you look at the circuit, one side of it goes to ground and the other side goes to B+. With the radio turned off and discharged, use a volt meter on...

I have 30 years into all of this myself, and on hf/vhf/uhf. I have seen nice improvements and I could hear stations that NO ONE else in my entire local city area of over 100 other operators could hear, it was AMAZING! Mind you this was back in 2008-2009 on these specific coax tests (my antenna...

Well, is it a newer style aluminum capacitor? estimate how old is it? if its another paper cap and just as old as that radio, like a pull from something else, then that might not be the best idea, but a aluminum cap would be better in place than that paper cap so since you have it on hand, if...

The cap can I was referring to is in the browning and trams, it is 3 caps in those units and not worth the expense when you can get 3 separate caps for much cheaper. Yes the large paper cap, it should be 80uf/450vdc, replace that with a new 100uf/450vdc.
