Can you substitute an RES164 for a C453?

Hello Donald,

Unfortunately this is not possible, because the RES164 is much weaker than the C453.

The C453 was only of short lifespan, therefore it is hardly available today.

A useful substitute could be the E443H or one of its many equivalents, such as RES964, L496D, etc.

However, there are some minor changes necessary to match the E443H to substitute the C453.
To give some clues how to do, I need to know the radio, in which the C453 is to replace.

Hallo Jakob,

I am very pleased to hear back from you.  I have sent you several e-notes, only to have them come back.  Perhaps you changed your e-mail address or I have thw wrong one.  Either way, I am very happy to hear back from you.

The radio in question is a Philips 634A.  I have had a terrible time with this radio.  The on/off switch has failed and, the original pictoral shows 15 resistors down the side.  Wouldn't you know I have 16 and they look original.

Best regards,

Donald

Hello Donald,

as direct substitute for the C453 you can use the PP430.

As C453 and C443 are at least very similar, you can take any types shown under “Identical to” or “Normally replaceable-slightly different” on both tube pages.

Due to spam attacks I was compelled to change my e-mail address some time ago. However you could have find my valid address here under my profile.
