Hi, I recently found in a second hand shop and purchased a 1932 Astor Aladdin model Z regenerative console receiver. It has three valves, E452T, E443N and a 80 rectifier . It is complete and in good contrition for its age. I have cleaned the chassis and checked the resistance and continuity with my multimeter of the transformer and speaker voice and field coil windings, RF coil, wire wound resistor and valve heaters and they were all good.
I would like to restore it and was wondering if anyone knew where I might find a circuit or even a similar regenerative receiver circuit?

The circuit is in the HRSA Astor book. It shows a 57 and a 47 in the circuit, but the brief description gives the original valve types as E452T and E443N with a 1561 rectifier.

Thankyou that is a great help. I really appreciate it. I will also join the HRSA.

Do be careful with the dial lamp. As you can see from the circuit it is floating, as are the filaments. Rotten rubber etc. can see them short.

I have seen the electrolytics grounded to chassis on these. NB it is back biased and that does not happen.

Thanks everyone for the posts. I replaced all the rotten rubber wiring with brand new cloth covered hookup wire, installed new capacitors but also left the originals in place but disconnected as they were in metal cans, and installed a new cloth covered 3 core power cable. The resistors are all wire wound and still in spec so I left the original wire wound resisters installed. After checking for shorts and slowly powering up the set with a variac it worked straight away. With a good aerial it has quite good performance receiving local stations for a simple 3 valve regenerative TRF receiver. Regards, Sam

Good to hear. How about some photos?

Hi, Included are photos of my Astor Aladdin. According to Rod Smiths book on Australian Radio this Astor Aladdin three valve model Z was released in 1931. Astor later re-released the Aladdin as a 5 valve superheterodyne in 1932. The tuning knob is not original as it was missing and the shaft had been snapped off when I found this radio in a second hand shop. Luckily I found the broken shaft inside the cabinet so I was able to glue it back in place with epoxy resin and I borrowed a knob from another receiver until I find a matching replacement.

The Aladdin has two Phillips valves, an E443N output valve, an E452T regenerative detector, and an 80 rectifier. I installed new capacitors and disconnected the original capacitors, repaced the power cord and rubber wiring. Originally this radio had a moving dial lamp on a pivot as a tuning indicator that illuminated the station call sighns behind the dial scale. Astor advertised this set with Spotolite Tuning. Unfortunatly it looks like the tuning indicator mechanism had failed in the past as someone had cut the dial lamp cable and removed the dial lamp and tuning indicator at some point in this radios life. That is why the grey dial lamp cable has been disconnected. This receiver is working well now.
