LW,MW. 3 Valves Battery Set
Made for Currys Circa 1928 High & Low TRF Working. |
|
The valve lineup is now Cossor 210RC, Cossor 210HL Cossor 215P. I constructed a univeral battery eliminator as featured in BVWS bulletin Vol27/1(excellent). By trial and error I have worked out the best voltages are, LT 2V, HT1 38V, HT2 120V, GB1,-1.5V, GB2,-4.5V. Nearly all of few parts in this set were faulty. I have guessed at the values as I have no diagram. The sound does sound a bit distorted. Any ideas why? The speaker is of the balanced armature type. The coil was O/C and was replaced by modifying another coil from an old pair of scrap headphones. The cabinet had stood somewhere damp and all the veneer at the bottom had stretched and peeled off. I re fitted it as best I could. The cloth is replacement. With the set was a piece of old curtain held in with drawing pins. Does anyone else have one of these? What was the cloth originally? |
