Hello , Has anybody done business with TE Systems in the past year ? Curious to know if anybody bought a high power UHF amp from this place recently . I returned my defective 4452g amp months ago and David Anderson still has not refunded my money...$993 . Still waiting for more than 9 months . I pretty much assume this place just ripped me off . Upon arrival via U.S.P.S. is when I discovered the " supposedly " brand new , freshly built and assembled amplifier has been dropped and bent over the threaded power studs and rear metal panel I immediately contacted David Anderson at TE Systems about this defective amp . He ...GASP !....acknowledges he knew the amp was dropped and damaged and determined it was something I could fix !!! Never occurred to David Anderson to think I am physically disabled and absolutely no means to fix a " supposedly " brand new , freshly built and assembled $ 1,000 amplifier using tools and such . Wants me to try bending back bolt and straighten out bent metal panel . SERIOUSLY , DAVE ??? $1,000 amp and you want me , a disabled person to fix what you broke ??? David Anderson also confessed he never checked the $1,000 amp after dropping it to make sure it still worked , nothing shorted out , no fire hazard , no explosion hazard ect.... I demanded to either replace this damaged amp or refund my money . David Anderson agrees to refund my money . Turns out that was just another lie . When David Anderson realized I was serious about returning this dropped and damaged amp he changed his mind. That's when I had to start playing the game of trying to get my money back . Going on a year and still no refund money . Contacted the [L.A. office ] BBB and he ignored them , twice ! Contacted the California AG office and he ignored them too , twice . Contacted the FTC , ignored them too . Contacted the FCC , not their problem . I contacted just about everybody I could think of trying to get my money back . I complained to the Michigan AG office and was REALLY SHOCKED when I got their reply from TE Systems . His excuse to Michigan AG office... David Anderson had determined I am not entitled to a refund because I am too old and have medical / mental issues . Went on to write.... due to my " supposedly " debilitating medical / mental issues and old age , I am not entitled to any of their products at all therefore not entitled to a refund either . David Anderson is older than I , that is a fact . I have emails to back up everything stated here , nothing is exaggerated . I have pictures to show what the damage is and the messed up , un-matched transistors inside . So anybody out there recently purchased a high power UHF amp from TE Systems ? Look at the serial number and tell me if he sold you my DEFECTIVE , DAMAGED amp to you . Check to see if TE Systems have sold YOUR returned amp to me . Might have changed the sticker but can not change the insides , I took pictures of the hodgepodge group of un-matched transistors and the bent up garbage he is pushing on me . The output transistors at these UHF frequencies got be matched or as close as possible to get maximum gain versus efficiency . Looks like this was a RETURNED amp for repair and never sent it back . Possibly stole it from the previous owner to sell again and again and again ... Fearing of being " stuck " with a bad amp....David Anderson sold it to me hoping I will not notice that it was assembled using decades old , un-matched Motorola transistors . Motorola stopped making these transistors more than 20 years ago . How can this amp possibly be " brand " new and the latest and greatest when built using decades old parts ??? Right now I have NOTHING , David Anderson of TE Systems has both my money and the pre-damaged amp . Sure wish somebody warned me that this place steals and lies and sells used , refurbished $ 1,000 garbage disguised as " new " . What a complete waste of money and my time trying to get my $1,000 back .
