Two weeks ago I found a stock of RF boards with SBL-1 mixers on them.
I thought it would be great for my son Etan to make some profit on his
own (and relieve me from some allowance...)
So, Etan will be offering used - and tested - SBL-1 mixers for sale.
I'll be helping him in the beginning, but that's his business!
Here's what he does:
- Parts are removed carefully, one at a time.
- Excess solder removed.
- Continuity and diodes tested with a multimeter.
- Each part is functionally tested as a mixer in a test circuit board
(17.5 and 14.7 MHz oscillators are mixed, low-passed and output
frequency is measured at 2.8 MHz with a P-P voltage threshold).
- Parts are mounted in conductive foam and shipped in a small box.
Since all parts are tested, Etan will also offer selected high-quality
mixers for a nominal fee.
These units are tested (at room temp) for a forward drop of less than
250 mV on each diode (at less than 1mA) and a spread of less than
3mV between the four diodes.
You get better efficiency and balance from these selected parts, beyond
the factory's worst-case specifications.
Prices are as follows (US Funds only):
1-5 units: $2.00/each
6 units: $10.00
12 units: $17.00
Selected High-Quality mixers: $2.50/each
Add $4.00 flat rate for shipping in 48 states, $8.00 elsewhere.

I definitely am associated with this operation, although it would have
been a financial disaster for me to carry out the actual work...
