This is an exact replacement for the RF in/out Antenna Relay in the Dentron MLA-2500, MLA-2500B. GLA-1000B, (and maybe more, see pictures) as long as your amplifier uses a 12vdc DPDT relay. Usable in other amplifiers requiring a good DPDT relay for RF T/R switching
Dentron did have some variations, so LOOK AND SEE If your amplifier needs a 3PDT relay, then you need to add a separate small relay for bias switching.However, I highly suggest you look at your amplifier to be certain. Why? Because I cannot be responsible for what was put in every single amplifier out there or what has been changed or modified since it was built! ONLY YOU can look and see inside your own amplifier!
I own FOUR of MLA2500/MLA2500B amps and all four use this same RF in/out T/R relay type designated on the MLA2500 schematic as \"RLY1\" (other Dentron amps refer to \"K1\").
See the pictures. Look at those gorgeous plated contacts!
Why try to burnish or adjust your old relay, just replace it!It is in an easy to reach spot.
Remember to BE SAFE - unplug from wall outlet, discharge the high voltage capacitors BEFORE attempting any repair on any amplifier!
You can use the terminals for the \"common\" of the relay contacts OR you can remove the wire going to the \"common\" leafs front terminals and solder those wires directly to the \"RF in\" and \"RF out\" connectors on the rear panel of the amplifier (this is what I suggest).
When these relays are sold - they are gone so maybe buy TWO and keep one as a spare. No extra USA shipping charge for buying more than one relay.It is a high quality DPDT relay with even better contacts than what I found in one of my MLA2500 amps, see picture.
Coil: 12 VDC
Coil current draw at 13 vdc - 125 ma
Contacts: DPDT rated for the FULL power output of the listed amplifiers
What is it NOT? It is NOT a cheap Chinese piece of junk! This is a HIGH QUALITY relay.
Can I provide support or repair advice to you on your Dentron amp? NO.
It MAY also be a good replacement in other Dentron amps or even other manufacturers amplifiers. This is up to you to determine. This will also be a great replacement antenna relay in many other applications but again, how you decide to use it beyond what we specify here as a direct replacement for the RF input/output antenna relay in the MLA2500 and MLA2500B is up to you.
Amplifier not included!
