Bmmfic,
Sad to say the relays are no longer avialiable for the 300-A's and have been gone for quite a while now.
That is the Major problem with them, the relay's go then the amp goes.
They used to make a Replacement Relay for them but again also history now.
You will find a lot of the 300-A's on Internent Auction Sites and that is the major reason they are there because the relays are shot.
About 2 years ago after 2 straight weeks of hunting the internet I was lucky enough to find a Stock set of 3 ~ NIB and the guy wanted $375.00 US, plus shipping for the three and I said No Way.
Sorry I can't be of more help.

Do you have the number on that relay? Look for something like R10-E1W2-V185. If you can't find the number, how many poles does it have or just count all the terminals sticking out of the bottom of the relay. |

The R10 relay should be easy to find. I'll check on the others. Look at the relay again. The "m2" indicates that it is a DPDT with the numeral being the number of contacts. If the highest terminal number on the bottom is a 10 then it is a DPDT. The "M" indicates the contact style and rating which I can't find an "M" in current production so you could just error on the side of caution and us a "W" which is rated at 7.5 amps. So you would need a R10-E1-W2-V185 for 7.5 amp contacts or a R10-E1-X2-V185 for 5 amp contacts. |
