Mosfet's
are fun devices, and capable of making a nice replacement finals they
are real cheap too. If your MOSFET is running hot. This is usually an indication of poor biasing or overdriving the gate. |
What are the EKL Companion Parts? The EKL ENXXX's have
the following on a ceramic substrate. He said the epoxy is very easy to remove so take one apart and have a look for yourself.

Here is a schematic of the EKL companion parts.

The following was posted on the forum from a member of the site. Just for the record
I thought I'd try the single mosfet in a DX33HML using the directions
provided. 2SC1969: ERF2030: Notes: The number one Question on the EKL MOSFET Application Notes. There has been questions
on where is R285 in the Galaxy EKL MOSFET Application
Notes. EKL must have just tested this on a EPT360014C board.. First we start
with EPT3600-14B (Dip IC9) Only dual final radios have this resistor (But not always Ranger put it on some single final models also.) See bottom layout right side for Location of resistor (it marked as 1K and I need to add a ref#) See this schematic (zoon in to IC9 to see R281 Pins 10&12 to gnd)
Now the EPT360014C (SMT IC9)
See this schematic (zoon in to IC9 to see R285)
Now print the following datasheets that explains the function for these pins is stroll down to S042P Mixer (Dip) and TDA6130-5X4 Mixer (SMD). R281 (14B) and R285 (14C) have the same function in the circuit. |
