The latest upgrade Immersion Gold , PCB use the latest technology Terminal Terminal Block SM and 6. 3 compatible plug reed.
PCB board marked with the names of all the above elements, the installation of just condemnation on the line, pay attention to the good part of the element can be positive and negative.
After many enthusiasts test phenomenon on the market due to the impedance of 4 ohms speaker impedance parameters between true and false mixed vacuity boxes often appear more popular chip burned so please choose 6-8 ohms speaker safer.
DC 30v-45v voltage can be a voltage different sound change, 32-40V, the safest and most suitable

Small, simple amplifier kit
Simple to assemble kits that work pretty well. However, make sure you drain the power supply caps before you hook up the amp, as advised in the online forums. I didn't know to do this and subsequently when I powered up the 7293s went up in brief flames. Ordered a replacement and installed bleed resistors.
