Hi,couple of items hoping someone may be able to id.

The meter, from the Type 123 Regulator Unit, part of the Marconi A.D. 7092 receiver setup:

Sorry try this?

Not much info other than that 'Pulse' was a manufacturer, prob T1163 is just a generic Audio & Signal Transformer?

The REACH status for this product is REACH unaffected. The HTSUS code for this product is 0000.00.0000. The manufacturer of this pulse transformer is Pulse. The product is currently obsolete and its moisture sensitivity level (MSL) is vendor undefined.

Any Pulse magnetic that has gone out of stock relatively recently and is now only sold by Chinese brokers, is extremely likely to be a compact DIL- or surface mount type ethernet transformer.

Thanks for the replies, cannot think of a use for the meter, the transformer may be of use as a inter-valve transformer.

Pulse Engineering, later Pulse Magnetics made a very wide range of wound magnetics. They were big in driver transformers for triggering thyristors, thyratrons as well as base and gate drive transformers for power transistors in SMPS-like systems. I used some of their packaged RF toroids to drive fast diode samplers.

Considering their usual stamping ground, it may be too low inductance for full range audio as an inter-valve transformer.

If the meter is 500 uA then I have a use for it, looks to be about the right size for a Larkspur ATU of which I have one with a o/c meter. Costs met of course.

Agreed, but do we have clues that the transformer in question is indeed the same as the Pulse one that went out of sale relatively recently and does not seem to have a picture anywhere? At least one Chines trader classifies it as an "IC" so likely a DIL cased component.

The transformer might be something entirely different by another manufacturer.
