Title: Identifying a choke
Post by: simonallaway on June 21, 2011, 10:53:21 am

I have a choke with the following stamped on the top:

M86C1
989 0730

My otherwise useful friend Google comes up with nothing, and it hasn't appeared in any discussion here. It measures ~160 Ohms with my meter. I was wondering if anyone had seen/used this part before, or if they knew any more about it.

Thanks,

Simon

989 EIA code = Marvel Electric, aka Magnetic Components

Looks like a typical 2 to 4H, 30 to 50 mA choke, more or less equivalent to a Fender 125C3A.

Thanks FYL. Marvel confirmed your theory:

"This is a choke rating 4Hy a 50maDC
Used on small guitar 5-10 watt amplifiers"
