Yep... > (bugs, reliability, operating manual/schematic availability). > steve > WA4BVO Bugs - none Reliability - good Operating Manual - Normally supplied with unit at the time of sale. Schematic Availablity - Included within the manual although I have a number of TPL Amplifier Manuals available for free download off the www.radiowrench.com/sonic web page. A phone call to TPL with a valid credit card in hand always seems to produce results if you must have the exact manual for your specific amplifier. TPL-Amplifiers are about as generic as they come... repair is not a big deal if you're used to working with modest - moderate power rf stages. **** Sidebar: An increase to this relative higher power output level can be a cautious road to travel. A circulator and/or trouble control detection circuit is pretty much a must have. Little problems normally not an issue at operation below the 60/80 watt power level can quickly lead to an equipment melt down. There is very little fudge factor and always no free lunch with 250 Watt operation at/near 146 MHz. cheers, s.
