[TenTec] Centaur metering question and 811A's vs 572B's

[k8mp at aol.com]

 Thanks for the info ?Kris.
By the way guys, I put new 811A's from DX Engineering in the Centaur last Friday and ran it hard in the 160 contest over the weekend with no problems.?
On Monday, I went to tune it up on 10 meters to chase the VP8. Well, the amp blew a fuse. Major bummer !!!
I took a look at the 811A's and sure enough, the plates had sagged on all 3 of them.?
I called DX Engineering and asked if they could help. Amazingly, they gave me a full refund, no questions asked. From now on, I'm buying from ham stuff ?them.
I was surprised to find out they had 572B's in stock so I'm gonna try those.

Joe, 
 
My Centaur also reads low in the forward position compared with an external watt  
meter.  I am not sure what the Ig reality is, but I have ignored the "issue".    
I just tune up as per the instructions and figure that it is tuned well with max  
output and do not exceed the plate current. 
 
It will be good to see others' comments on this issue.

 The "FWD" meter reads low as compared to my in-line watt meter, which I know is  
accurate. 
I'm OK with that but I'm concerned about the grid current reading, since it uses  
the same meter and switch. (I've seen a lot of scuttle-butt about the metering  
switches being a problem) 
Any input is welcome.
