[Lafayette] Still works

[Toshikazu "dan" Sakakibara]

Hello Pete, Ron and the list;

   I'm confused about the HE-80 and HA-225. In my understanding
  the HE-80 came first, then HA-225 replaced it. I saw ads on QST,
  that the HE-80 appeared in early 1964, and the HA-225 appeared
  on December 1964. I don't have Lafayette catalogs so I don't
  know if the ads on QST properly reflects when they were
  introduced to the market.

   From my observation the differences are;

   1: HA-225 covers longwave, instead of BC.

   2: HA-225 has a separate heter transformer. The LO and
      mixer tubes are heated up even when the power switch is
      OFF.

   3: In HA-225 the main and bandspread tuning caps are covered
      by a steel box for better shielding.

   4: In HA-225 the audio output transformer is mounted
      with 45 degree angle. Reason unknown. Possibly to reduce
      hum.

   5: BFO tube is mounted on a sub chassis, possibly to reduce
      the BFO leakage.

   6: Dial string route is different.

   7: HA-225 uses coaxial cable from antenna trimmer cap to the
      coil pack. HE-80 uses regular wire.

   8: Shape of the chassis hole for the IFT mounting different;
      HA-225 has less opening, possibly to increase shielding
      effect.

   It seems that the HA-225 has a lot of small improvements
   over the HE-80. If HA-225 came first then HE-80, I would
   say the HE-80 got a lot of cost reduction....! :-)

   HE-80 is completely (but cosmetically) identical to the
   Trio (now Kenwood) JR-60. It appeared to the JA market
   in 1963.

    My guess : HA-225 was newer than HE-80 in its design.
    but radios without BC coverage did not sell well in the
    U.S., so the older JR-60 was called and remodelled as
    HE-80..... just a guess.
