I will update you sometime regarding equivalent Transistors that may work with this VHF Receiver. It might be possible but I can't guarantee, Think that the 2N3819 FET may work in the oscillator circuit. A 3SK88 or 40602 Dual Gate MOSFET should also replace the 40673 Mixer transistor     


Switches S1A, S1B. Double pole toggle or included on VR1 volume control as in the prototype. 

Telescopic aerial. Recommended is the directional one, I use in the prototype and is a available at the time of writing from Maplin Electronics Code JL11M 

Circuit Board. Available from Maplin Electronics as Plain Board 3929 Code JU37S and was used for building the prototype

Speaker 8 Ohm 1 Watt minimum.

Wire 16 SWG enamelled copper wire for winding coils 

Tinned copper wire for interconnections on circuit boards

Battery Holders 2 X PP3 Clips, Code HF28F Available from Maplin Electronics 

2 X 6AA Battery Holder with PP3 connector, Code JK78K Available from Maplin Electronics

Batteries 12 X AA Zinc Carbon, Recommended for testing the receiver for the first time.

12 X AA Alkaline for continues use is recommended, Provided you are satisfied everything is working OK.             

Vero pins. For mounting the VHF RF Coils and interconnections on circuit board

Equivalent Transistors

Although I cant guarantee these are direct replacements and may call for slight circuit modifications, regarding the DC bias conditions, Here are some of the ones I picked out of the Bernard Babani guide book BP85 dating back to July 1988.  

TR1/2. 2N3819 Equivalent replacement. MPF108. MPF112. FE3819 All American.

TR3. 40673 Equivalent replacement. 3N159. 3N201 All American.

TR4. BF244B Equivalent replacement MPF102

TR5/6. BC547 Equivalent replacement. No information so far to date.

TR7/8 2N2369A Equivalent replacement. 2N2369. BSX93. BSY19. BSS11 All European. 2N3227. 2N4275. EN2369A All American. 2SC889 All Japanese.
