Description

Heathkit SB-620 Scanalyzer Panoramic Adapter / Spectrum Monitor Collector Quality Cosmetic & Working Condition

 I powered up this Scope on my bench and it has a nice focused trace. I have not used this SB-620 as I do not have a working radio. It came with the SB-301 / SB-401 station I have listed.

 This beautiful Scope was purchased about 30 years ago and was part of a large collection that was displayed in a clean dry environment and not used for all this time.

As with most vintage gear, it may be improved with new tubes and it would be prudent to replace the electrolytic capacitors Before they fail, but it appears to be working as it should. 

I am selling it as is, as described.

  I have been packing and shipping heavy vintage gear for over 30 years and this item with be packed better than any paid packing service. 

 I will include a nice copy of the manual.

 
The Heathkit SB-620 Scanalyzer is a classic late-1960s/early-1970s panoramic adapter (spectrum monitor) designed to visually display signals around the tuned frequency of a receiver. It functions as a narrow-band spectrum analyzer, showing "pips" for signals ± a selected width from the receiver's IF. It matches the SB-series styling (e.g., SB-301/SB-401) and is highly valued by vintage station owners for spotting activity, monitoring band conditions, and analyzing signal quality.
