Hello,
the replacement of a ECL86 by other tubes is not possible or needs to much changes in the radio. There are many internet shops where you can buy new ECL86 for medium prices.
The only other tube which is possible, is the PCL86 from old TV instead of a ECL86, but for the PCL86 you need nearly 16 volts for the filament (ECL86 has a 6,3 volt filament).

Best regards,

Roland

I know that; PCL86 has 14 volt heater but I didn't know , how can I get 14 volt current from in my radio because my radio has 6.3 volt current for valves.

Hello inecik,

here you can order an ECL86:

It's rather expensive, but it seems that the tube is new (NOS).

Hello,

I am afraid there is no possibility using a PCL 86 in your Radio.
Perhaps a little transformer is availible? I suppose, that`s the only chance for you.

Best regards,

Hello,

in this case, I'm very sorry!
Finally we found an ECL86 for purchase, but now the shipping is too expensive.

The PCL86 needs 13V AC for heating. The only solution would be a separate transformer with this current on his secondary side. Take care of the 300mA.

So long,

Hi,
you can try voltage-doubling (DC from AC) as described here:
http://www.b-kainka.de/bastel89.htm
Burkhard shows on the bottom of his story how to make 50 Volts DC from 24 Volts AC. This will work with 6,3 to about 14 Volts as well. You will only need two diodes and two caps.

Best Regards,
Jean

Hello inecik

you can use also a small additional transformer, with secondary 12V 0.3A , this will work for heating the PCL86. Disconnect the 2 pins No. 4 and No. 5
from the 6.3V heating circuit, and connect 12V to the pins. Do not forget to connect one pin of the 12V to ground. Thats it.

Hallo Armin,

mit mir kann man außer in Englisch auch noch in Deutsch reden.

Als Adressat Deines Tips meintest Du vermutlich 'inecik'.

Hallo PL504,

weiter oben schrieb er, daß er in der Türkei lebt und daß ihn der Versand sehr teuer käme. Das Problem liegt also weniger beim Kauf.

So ein kleines Päcken kann per Einschreiben verschickt werden, nennt sich wohl dann Briefsendung ist aber trotzdem ein Päckchen.
Kostet um die 13 Euro mit DHL.
Falls DHL nicht die Preise geändert hat, sollte es also kein Problem sein.
Man muss den Verkäufer nur auf diese Möglichkeit hinweisen.

Gruss Eisenkern

Moin!
Other names for the ECL86 are 6GW8 or CV8297.
On eBay item no. 280422427309 four matched Tubes are sold from Istanbul.
That might help.
