Description:

The HL-4000 the FIRST HF amplifier made by THP. The 4000 was not an export model amplifier. It is believed that only a handfull were ever made and therefore it is almost impossible to even find a picture of one much less the specifications or the manual. (If you have any info please let us know)

We believe that the Amplifier pictured on JA1DJW QRZ Page is the HL-4000 but the picture is so Grainy and old that we cannot be certain.
