This is a serious proposition. I’m trying to expand my knowledge. The first person based on TIME/DATE STAMP who answers each of the following questions will be paid $100 via PayPal friends and family on the same day they respond. All questions must be answered and not haphazardly.
As you know I have fixed the FatBoy 4 pill amp by modifying the feedback circuit with 5% tolerance components and decreasing resistance. The end result is both input/output impedances were improved and the amplifier is working fine with no issues.
I request that I can ask ONE/A Single question following the answers.
Here are the questions for which I’m seeking answer but until now have received no response.
Pictures of amp are posted below.
1. What is the purpose of the orange (radial) capacitor going from ground to the relay?
2. What is the purpose of the mica capacitor going from ground to the relay?
3. What is the purpose of the disc capacitor going from one lead of the orange capacitor to one leg of the RF sensing transistor?
4. Then in all that mess there is a diode (I’m assuming a common variety) going from ground to the center leg of the RF sensing transistor?
5. On the opposite side there is a large orange disc capacitor going from ground to the relay.
6. What transistor is being utilized for RF sensing?
7. Should I upgrade the keying relay to something more stout?
8. I want to also install an RCA jack/or re-purpose the remote jack so I can manually key the amp and bypass the RF sensing when desired. Does this involve adding a second relay SPST to bypass? What type/rating relay is needed? Would like to still have the ability if possible to use a switch to go between keying jack or RF sensing.
9. What’s involved if I want to add bias/delay for SSB
PS: This is not a joke and not meant to insult anyone. I realize that a person should get compensated for their technical expertise.
Thanks in advance
