Radio: Medion MD 82479 of (or) Medion Life X640044 transfo of uitgangspanning

Tue, 25 Feb 2020 15:15:00 -0700

English version below.

Van mijn moeders Medion MD 82479 of Medion Life X640044 is de kleine transfo defect.

Ik ben op zoek geweest naar een technische handleiding , doch niet gevonden noch iets anders die me kan helpen..

Het betreft onderdeel T701A1 ( is de aanduiding op de printplaat)

Opschrift op de tranfo : Fuse 125°C K3 / N288BF.

Afstand tussen primaire en secundaire klemmen 30 mm,

secundaire weerstand 7,6 Ohm.

Als er iemand mij de secundaire spanning kan vertellen ben ik al gered.

Een wisselstuktranfo omschrijving is beter , en een schema met specificaties is nog beter.

Gezien de radio, Boxen en bediening aan de pas geschilderde muur bevestigd is kan deze moeilijk zonder veel schade vervangen worden.

Alle hulp is welkom .

The small transformer of my mothers Medion MD 82479 or Medion Life X640044 is defective.

I have been looking for a technical manual, but neither found nor anything else that can help me ..

This concerns part T701A1 (is the indication on the printed circuit board)

Inscription on the transformer: Fuse 125 ° C K3 / N288BF.

Distance between primary and secondary terminals 30 mm,

secondary resistance 7.6 Ohm.

If someone can tell me the secondary tension, I am already saved.

A spare part transformer description is better, and a diagram with specifications is even better.

Given that the radio, boxes and controls are mounted on the newly painted wall, it is difficult to replace it without much damage.

Any help is welcome .

BOSE Wave Music System CD Player FM AM Radio AWRCC1: How do I dislodge a cd from the player?

Tue, 31 Mar 2026 19:54:33 -0700

I have a cd stuck in my Bose CD player. The eject button on the remote will not dislodge it. I'd read, on U-Tube no less, a few years ago that shaking the player would work Didn't and seemed a rough solution.

DAB Radio: Bush Radio powers on with new power supply but wont tune.

Sat, 07 Mar 2026 19:54:35 -0700

Bush radio original power supply is 5.9v the lead became dodgy so I bought a third party replacement, sold as suitable for the model of radio. Replacement power supply is 6v. The radio powers on and the clock and tuner displays on the colour screen on the radio work properly, but the radio says that every station is 'not available' . Swap back to the old power supply, which isn't suitable long term because of the dodgy lead, and the radio works perfectly. The only other difference is that the old power supply has a large interference surpressor on the cord which the new one doesn't have - or if it does have it - it is in a much smaller fitting nearer the output plug. What could be causing this behaviour Any solutions?

Bose Wave Radio AWR1-1W: Power cord chewed off by dog

My dog chewed the cord off of my Bose WaveRadio/CD Model AWRC-1P. It has a non-removable part that’s attached to the back of the radio that’s a part of the power cord. How can I replace the cord if it can’t be removed from its base? What are my options? Buy a whole new radio? I checked and it’s no longer under warranty.

CB Radio: President Grant AM SSB needs help.

Sat, 10 Jan 2026 00:24:28 -0700

I have a President Grant 40 channel. AM SSB. It appears to be recieving as it sounds like it when antenna is connected. It has a external VFO. Antenna is nice at 27mhz. Its new to me and I havent had the back of yet. Questions.

What exactly is my VFO for?

My signal strength needle does not seem to work,does not move much?

My select switch could be bad as I have LSB but it is dead quiet on AM and USB

The radio come with a small kenwood mic, which did not work, another new CB mike I had here seems to work. The light comes on when triggered. The VFO has an on off switch, do you think I will ever use it? When it triggers the signal meter shows a small movement.

The signal meter rises up with modulation when I key the mic and speak.

Radio: Channels dropping out vintage KLH-200 radio

Thu, 23 Oct 2025 17:22:55 -0700

Hi, I recently picked up a vintage (1985) KLH radio so I knew it would need cleaning. I cleaned all the pots which reduced crackling, but now I still get left or right channels dropping out constantly. When I touch the aux switch it will briefly fix everything but it drops out quickly (i tried to clean it but it'll need some disassembly.) Any advice would be appreciated.

Radio: How to I take apart my Sony ICF-P26 am/fm pocket radio?

Sun, 24 Aug 2025 07:44:45 -0700

This is a great portable radio but after only 6 months the volume control potentiometer needs a clean. The volume jumps to maximum at some points in its travel. I think I can clean, or replace, the pot once I open the case but can't manage to open this case. I removed the two screws inside the battery compartment hoping that would allow the case to hinge open, but alas - no budge. It must be held by clips that grab on assembly. Any ideas? Here is what it looks like:
