Restore ve 301 w

[Jba999]

Hi.
I have an old radio ve 301 w.
When there is power on it, there are lights and speakers vibrate. But no sound.
I do not think it works.
I want to replace all the components because I don't know what is broken.
Should I change all the opponents, and the capacitors in the same size.
And what can replace they old tubes.

Where can I get an am transmitter?

I hope you can understand me.
Sorry for the Google translate.

hi, welcome here.

At first you should replace the old capacitors. The big block and other paper types. The old tubes may work after all these years, i think there is no need to replace them at the beginning.

Which model is it exactly?
There are two fundamentally different types:
The VE 301 W (with round speaker cutout) has no dial illumination unless it was installed afterwards.
The successor model VE 301 Dyn W (with rectangular speaker cutout) has an illuminated linear dial.
The manufacturer does not matter, because many companies built the radio in an identical design.

Are you familiar with the operation?

With this radio, tuning in a station is a little tricky. It requires adjusting the frequency setting (middle rotary knob) and the feedback (right rotary knob). The latter may only be turned up until just before the point at which the noise changes. If you turn it up too far, the receiving stage oscillates and the radio basically works as a transmitter. Then, of course, interference-free reception is no longer possible.

Hi. Thanks.
Ve 301 dyn w.
Will buy an "Am transmitter" , with aux or bluetooth so I can test if it works, but can't find some one.

Please replace the mentioned capacitors first.

If they short (or are already shorted), they can use all sorts of mayhem, including destroying irreplacable (without sacrificing another unit) components like the mains transformer or the field coil of the speaker. The final and rectifiers tube can also be destroyed if they were still working before, you can occasionally get them, but they ain't gonna be cheap in those days (expect 40-100€ each for a new one).

If you REALLY need to power it up again, put a (classical, tungsten filament) 40-60W lightbulb in series with the mains input. If it lights up brightly for more than a moment after switching it on, cut the power IMMIDIATELY. It should only glow dimly in normal use. If you have access, powering it up with an (ideally isolating) variac is also very advisable.
