    The 9805A by Victor is a really good, moderately priced meter. I like it particularly well because it will not only do the standard voltage, resistance, and current measurements, it will also do inductance, capacitance, and frequency. And, the value ranges provided are in the ballpark for what we see in PTP guitar amps. It also has a temperature probe which is great for monitoring transformers and other devices for problems. At this price, if you blow one up it's cheap enough to just toss it and buy a new one. Incidentally, I've had a 9805A for almost two years and I haven't blown it. On the contrary, I decided to try one because my Fluke died, it wasn't that old, and the repair cost was too high for me to justify. I think Fluke just replaces the entire guts as standard repair.

    The X830L also tests transistors and will measure current up to 10 amps. It also features a momentary (5 seconds) blue backlighting for the display. No big deal, but kind of cool.

    The DT9205A has a 20 amp range, measures capacitance, tests transistors, and has all the standard Volt-Ohm ranges. It also has auto power off, which must have been invented for people like me. The position (viewing angle) of the display is adjustable, which is kind of a cool feature.

    Seems everyone could use a decent amp cradle for builds and repairs. Note: Not intended to be used as a performance stand for your entire amp. This is for your amp-tech bench, to hold the amp chassis while you work on the inside, etc.

    The Tru-Load is a bench dummy load for testing amps. It employs a combination of inductance and resistance. The inductance is provided by an authentic moving speaker voice coil and motor assembly. A BNC sample O'Scope port is also provided as well as banana jacks to monitor the load voltage. The Tru-Load is switchable from 2 to 16 ohms and will handle 200 watts continuous.

    This item is hand-built to order, to ensure the best attention to detail is paid to its construction.  We build them one at a time, on a table - not hundreds at a time on an assembly line.  This allows us to reduce the margin for error and produce an overall higher-quality product.  Please allow at least 7-10 business days for your order to be built and then shipped.
