[TenTec] Titan 425 Amp

[Hampton]

Fred,

The Titan 425 amp you have may not be an export model, but rather an early version.

I have one, SN 00319 and it has the front panel Hi/Lo voltage switch you refer to. 
(I run it on the Hi voltage side.) I am the second owner and I believe it was initially purchased from the factory ~1986. I bought it in 88.
For reference it has the dark green/brown paint. 
I have run this amp on 17 & 12.  
You potentially have a GREAT amp that will not quit. 

Jim Brown who replied earlier is a good resource.  (Thanks Jim)

73,
Hamp WS5C

Hello all,

I just recently bought a Titan 425 (used of course) and am trying to determine when the amp was manufactured using the serial number.  My search of the web must not have the proper search parameters as I can't find any reference to serial numbers for the amp.  I believe it to be an export model as it has the LO/HI voltage switch on the front.

I would also like to find a manual for the export model (digital or scanned) if there are any to be had.  I've heard that there may be damage to the amp if I run it on 12 & 17 meters without some sort of modification.  I have try loading those bands into a dummy load and the amp seems quite responsive.  Any information about 12 & 17 meter modification and/or sources for the manual would be appreciated.
