Has anyone modified any Huntron's to provide Lower Test Voltage levels ?

hi,

Has anyone modified any ( likely Older ) Huntron's to provide Lower Test Voltage Levels ?

( Newer Huntron's seem to have some capability for this ).

I am seeking details about this because  I have a need to explore, in-circuit, components from "underneath" the Turn-On voltage of standard semiconductors, to examine Passive circuit elements,
  As well as to explore some modern and experimental semiconductors having Turn-On voltages in the ranges of, say,  0.2V up to 6.0V (switched steps), and would like to fine tune those with adjustable Pots, etc.

 A third reason is the exploration of 1950's - 1960' semiconductors where the standard (older) Huntron Lo Range Test Voltage level of 10V (7Vrms) is too much and these early semiconductors are "fragile",
 as it were.

  { Forgive me, I only have a Huntron 1005b-S1, and am hoping to modify my unit for the above, and apologize for posting here, ... but this is a general question }.

  Just found the following older Post, concerning similar & possible BJT Transistor hfe damage.

... but I still want to Modify my older Huntron for much lower Test Voltage Levels than it currently has !

thanks,

Hi cog7997,

Welcome to the forum!

Due to safety considerations and potential liability issues, we are unable to provide any support, guidance, or assistance related to the modification and alterations of any current or legacy Huntron Products.

We understand the interest in customizing or adapting our equipment; however, such actions fall outside the scope of our support policies and may compromise the safety, reliability, and intended functionality of the devices.

That said, you are correct in your understanding of the Tracker 3200S specifications. The voltage range for this model begins at 200 millivolts (mV) and increases in 200 mV increments up to 1 V, offering a total of 24 voltage ranges. The Tracker 2800 and 2800S have more limited voltage ranges but also include a 200 mV range, with the next step up being 3 V.

We appreciate your understanding and encourage users to operate Huntron products within their designed parameters to ensure optimal performance and safety.
