I'm at a loss on how to find a Vactrol, to use in place of a terminating
resistor in a K9AY loop setup.
Living in Sweden, the market is somewhat smaller than in the US... But
postal order, or e-business, might be a solution, so any suggestion is
The earlier used VTL3A, in various construction, has been discontinued
according to recent info from the company:
"The VTL3A series incandescent optocouplers were discontinued about 5-7 years
ago. We do not have a direct replacement part. The only optocouplers we
are making today are LED units. You could try our competitor Clairex at
http://www.clairex.com . They have a part CLM310 that might be a close
equivalent to our VTL3A27."
Ayone having any ideas on this CLM310 part?
