1. [Amps] FL-2100B value of shunt in the Metering Circuit (score: 1)
Author: VE6TI <ve6ti@telus.net>
Date: Fri, 15 Dec 2006 16:39:13 -0700
I have been over hauling an old FL-2100B amp and found that the meter shunt, R3 on the schematic, looked a little cooked and upon examination noted that the windings were physically, if not electrica

2. [Amps] Grid Current Metering FL-2100B (score: 1)
Author: VE6TI <ve6ti@telus.net>

carl / kz5ca and I have exchanged some info regarding 572B's and the tendency of the amp to blow the 33 ohm 1 watt resistors in the grid bias circuit of the FL- 2100 and the lack of grid metering on

3. [Amps] Addendum to Grid Current Metering FL-2100B (score: 1)
Author: VE6TI <ve6ti@telus.net>

An addendum. The Heath manual states that the grid current should not be allowed to exceed 100 ma and if it does then it is necessary to reduce the drive from the exciter. Makes sense and I am assumi

Thanks to all the responded to my inquiry earlier in the week, the suggestions were helpful and lead to discovery that I had indeed tapped into the relay coil line instead of the RFC. Both lines are

I just noticed that I had not copied the reflector on my response to Carl's question of how I monitored the Grid current on the FL-2100B so I am posting it now. Any comments about how I am proceeding

Hello Fred I have purchased and used 572B's in my 2100B from both Penta labs and from RF parts. Both sets worked well once I got the other problems sorted out. While the RF parts are marketed under t
