Early Spendor BC1 Crossover question

[The Basilisk]

Hi all,

Can anyone tell me the value of the small resistor in the supertweeter part of the crossover on an earlier type Spendor BC1 (1975, Blue Alnico woofers).

Later crossovers (ie early 1980s) used a 33 ohm 5 watt, same as in the bass driver section. However, these earlier ones have a slightly different circuit configuration, and the tweeter resistor is physically smaller (and itself is configured differently in the circuit).

Any help appreciated

22 ohms on this one. I sold these in late 1976.

Thanks Dave !!

Yes that looks like the same crossover indeed.

Cheers
