NOTES ON TRANSFORMERS TYPES IN XRELL kMPLIFIERS
There have been transformers made by two different manufacturers
used in the new Programmable series amplifiers. During the time
period of March through September 1988 transformers from
Avel-Lindberg were used. In September 1988 we began using
transformers made by Holden & Fisher. There are differences in
the wire color codes and some of the secondary voltages. A
separate sheet is included here that details these technical
differences. Please refer to the visual descriptions below to
determine which type transformer is in your unit before
proceeding with any work.
AVEL-LINDBERG: The transformer can is painted a matte black
finish. The upper corners are rounded.
HOLDEN & FISHER: The transformer can is painted a glossy black
finish. The upper corners have almost no radius, and are
virtually squared-off.
