Type 3 MK2 (B2) Spy Set Radio. Suitcase Ver.
Group,
Have anybody any knowledge on the type(s) of headphones that were supplied with these sets. Where different types supplied? Would the DLR No.1 be standard issue. I know a quantity of light weight headphones were supplied to the Stone Bridge factory from USA. but they could have been used on different suitcase radios. I would be grateful of any information. Thanks in anticipation. Stuart. |

The manual says "Telephone headset (L.R)" 120 ohms resistance, impedance 800 ohms at 800 c.p.s.
My set has Multitone Electric headphones.
