Just to let you guys know, The Stryker was too much power for the amp.
I hooked up my Cobra 29LTD and was able to adjust the radio with amp on high to a 80w dead key and 200w out. I am Happy with these results.
Thank you everyone for all the information and most importantly your help.
73's
Jeff,
Thank you for the resistor info. order and on the way.
Can you please show me how you bypassed the whole switch and went right to the input transformer? What wattage output are you getting out of the amp?
What's the input watts, dk, swinging watts from radio?
Thank you guys for the information and a place to start.
Fairly new to all this and interested in learning as much as I can.
Thanks again, Have a Great 4th of July and 73s
@freecell,
So if I change out the 455's for some 1446's would that be better?
@9C1 Driver
I am using a Dose TFB 3001 meter
Radio is a Stryker 955HP
Low power @ 2watts with a 20 watt swing.
I am not able to lower dk to 75-80 watts
I think the radio is too much for the amp?
Jeff,
Thank you for the information.
The amp has 4 MRF 455 9245 Malaysia F Transistors. If I'm only getting 150 watts out @ 2 watt dk swinging to 20 watts, is that ok or is there something wrong with it?
Greatly appreciate your help.
By the way someone had a 39 ohm resistor soldered to the Med...
I just picked up a used 400 and 2 watt dk and swinging to 20 watts and I'm only getting about 250 watts on high. Can anyone tell me if something needs to be changed out. By the way it has 4 MRF 455 9245 Malaysia F pills in it. I believe they are 60watts each.
Does anyone know the values of the resistors R7 and R8 and if so, where can I buy them?
They look heavy duty to me.
also I seen on this site different people saying that the 400 only needs 1.5 - 5 watts dead key into it.
Should I input 1.5W, 3W or 5W into the amp?
Any and All Information will...
