Hello Mr. Subramaniam,
I too have same radio (model B5CA37a). It is under repairing. I am looking for those push buttons ('Bass & pickup) since spring of one of the push button is broken due to rust and also latch is broken. Therefore, wanted to know if it is possible to get the above mentioned assembly? Thanks.

Regards,
Sanjay Karambelkar

Respected Shri Parasuraman S,
I am writing you from Kolkata, India. I am in search for a extremely good sounding valve radio (preferably with stereo fm reception} in fully restored condition. Should have strong and very very clear reception capability. Can you help me in this regard ?

The wavechange switch is a large sliding wafer type which, although OK in this set, looks to be a likely trouble spot due to its flimsiness. This is mechanically linked to the rotary knob on the front of the case.

In reply to SAJID RAUF RAJA.

Forgot to mention that after aligning the RF Oscillator Coils, you may have to tune the Antenna coils. In the same method explained for RF Osc., tune MW Ant coil for peak of any station nearest to the closed gang position, and then open the gang fully and tune for any weak station nearby, then adjust the antenna trimmer for best result. Repeat this a few times, until you get very good signal at both ends. Follow the same method for SW bands as well. You can use RF Generator, if you have, and do the same at both ends feeding the signal as per specifications of the coils used. All the best!

Just type the valve numbers in Google search, you might find it there. Otherwise, look for my previous article on Valve Radio, where I have given links of certain valve specialists. Look through the data published there or put up a query! (Radio Museum is another site that provides technical info) All the best!
