Hi all,

About three months ago I sent an audio interstage transformer for a Philco 38-690 (Part 152 on attached schematic) off to Heyboer Transformers to be rebuilt; it had an open primary. Just got it back today and the resistance readings are WAY off:

Primary should read 475 ohms. It reads 186.
There are two secondaries that are supposed to read 260 ohms. Each reads 64-73 ohms.
The third secondary reads a few ohms; not sure what the spec is, as it is not listed on the schematic.

What should I do? How crucial are the exact resistances? These seem pretty far off; send it back to Heyboer? Give it a try?

PS: Ignore purple marks; they are not pertinent to this question.
