Never use GC Electronics black anti static alignment tools around high voltage. Used one on a neutralization capacitor in a Kenwood ts830s and it shorted to the chassis. POW!!

I have a HP 8640B with no RF output. The Power meter light does not turn on. The unit turns on but no RF output and no counter output movement when the internal frequency dial is turned. The power supply LEDs are and no -5.2VDC. I removed the RF Divider Filter Assemble and the -5.2 VDC is correct. Can you please provide suggestions on what is drawing the voltage down to 0VDC? The rectifier boards and filter caps are good. Al

Hi I'm in North Wales, if I made one of these should it cover most of the UK? I can only pick up Wirral London control and Liverpool airports right now using a standard RTL SDR antenna that came with the dongle. I do have another antenna a Eightwood 4G LTE Antenna but still just Liverpool and London control. Thanks
@Andrewausfa6 ай бұрын
Hi, not sure if this would work with SDR efficiently across all bands as it's air band specific. It should be OK for normal 'Air' but not for scanning MW through UHF. Does that make sense? I do have an SDR dongle but found it absolutely rubbish so I stick with my 3500XLT. I'm in Cambridgeshire and can pick up Manchester control no issues.

That was a bit of an "ouch!" at the beginning of the first part of this pair of videos! So good you managed to get it all back together, though, Andrew. Periodically, I go through sessions in my life of tracking down the makes and models of past electrical goods that have been in the family and at last it appears that I have, at long last, identified the radio that Nan - my maternal grandmother - had. It was quite an attractive design on Philips' part and certainly distinctive. Thanks for the insights into repairing parts of the circuitry, whereby I think I really learned something should I ever decide to delve deeper into effecting such tasks. Perhaps you should have pointed out that, as they say, other brands of porridge oats are available, unless you're sponsored by Quaker! On that subject I do like the branding of your channel, as that is the make of a vintage valve radio I have, that works in a partial - hardly any LW and MW and not much more SW, but plenty of VHF/FM - and on and off sort of way - periodic 'buzziness' - and, indeed, I recently featured the VHF3D 'Stereophonic' in action as part of celebrating a decade of KZbin membership. I hope you enjoy it should you drop by my channel!

So the pre-amps working but nothing out of the main amplifier? Have you checked the speaker leads are connected to the speaker? Sounds obvious but can be as simple as that. Other than that it's either between the input to your amplifier chip from the pre-amp or from the chips 'out' leg to the speakers. Could be a fried chip, it does happen.

I´ve a nice Hitachi radio it´s a Wh-859D with Germanium transistors that is failing, sometimes there is no sound at all. It was constructed using these transistors numbers: 2A A 131 (Freq. Mixer) , 2AS A130 (Local Oscillator), 2S A12 (.F. Amp.) , 2 S B75 (A.F. Amp.) , 2 S B77 (A.F. Amp) , and 2S B156 (Power Amp.). I´d love to change them to Silicon transistors. Which easy to find and equivallent transistors would you suggest me to find here in North America?, Thanks in advance from México.

I, too, have the model 470A in my collection. Even though it is a 'short' Superhet, it gives a very good account of its self. There seems to have been two A.C. models of the 470A.... The "home-market" version, using the "Golden range" valves, "FC4", "VP4B", "PEN4DD", "1821", like yours and mine; and an "export-market" model that used the "red E" type valves on side-contact bases, "EK2", "EF9", "EBL1", "AZ1". It also had more continental stations marked on the dial without the BBC "National" & "Regional" stations. I have heard that there was a "Universal Mains" version made, model 470U, which also had a "C1" Barretter ballast resistance for the heaters. But I don't know the valve line-up on the 470U.

Just found this page.I own the exact same model,and it performs far better than my DR/RF31 receiver. I will point out that the Band changer/slide function on the circuit board will fail at some stage.I owned the DR/RF 49,big black radio with metal case.This radio performed for 10 years after I bought it second hand.One of the very best National Panasonic radios I had ever owned untill one time it became non operational completely on HF bands because the band slider jamed up.I managed to unattach it off the circuit board,because it is an integral part of the board,and found the very tiny fingers that slide back and forth had all curled up and twisted becomeing completely non operational.I could not find another circuit board that had not had the same problem.I notice the same band selector system is used in my DR/RF 28,yet so far it has not caused any problems.So for owners of these fine radios,please be aware of this.
