Heathkit Ha10 Warrior Kilowatt Linear Amp Must See

Heathkit Ha10 Warrior Kilowatt Linear Amp Must See



This si a model ha-10warrior kilowatt linear amplifier made by heathkit. It is in very good cosmetic condition as seen from photos. I powered up this amp and all tubes came on, power light, high voltage light, fan ran, etc. I read 1700 volts high voltage on the meter. I cannot test on transmit. I also acnnot guarantee this amp works properly or to specs. The 4 output tubes are rca usa made 811a.
The 2 rectifiers are rca uas made 3b28. All tubes were testde on a calibrated tv-7d/u tube tester. Teh 811as tested 44/50/53/49 (min should be 36). The rectifiers tested good also.
Someone added a larger rotron fan and the installation looks good. Cannot determine if other mods were done since i do not have a manual. Looks like a 12v transformer and possibly a tr relay has been added.
Copmletely self-contained desk-top kw linear. Exclusive internal rf shielding for maximum tvi suppression. nIterlocked switching of hv for maximum circuit protection. Low cost, high quality, 811a and 866a tubes. Fan forced-air cooling-clean, functional styling. The heathkit warrior puts high quality, power-packed performance within easy reach of every amateur who wants a big boost in transmitting power! The warrior is a completely self-contained, desktop, kilowatt linear loaded with spceial features. At only half the cost fo comparable equipment. Note these many quality features. Amplifier and pwoer supplies for hv, filament, and bias are built-in. May be driven by a 50 to 100 watt output transmitter (no matching or swamping network required). Stable grounded-grid circuit puts part of drive in output for up to 70% efficiency. Four paralleled 811a's and two 866a's force-air cooled by a built-in fan. Large oil-filled 8mfd, 2kv capacitor and 5-50 henry swinging choke for high peak power output with low distortion. Provides a high degree of overall stabiliyt in conjunction with the grounded grid circuit design. To prevent accidental application of hv beofre switching on filament and bias. For maximum protection against tvi. Gives constant output to scope regardless of frequency. 16 gauge steel chassis-1/8 aluminum front panel-welded one-piece cabinet. All these features are combined into an extremely well laid-out circuit design that makes assembly an easy task which can be accomplished in a few evenings. Maximum power ipnut ssb-1000 watts p.

Output circuit variable pi-network (50 to 75 ohms). Driving power required 50 to 75 watts-depending on frequency.

Input circuit broad banded-requires no tuning. Input impedance 50 to 75 ohms. Band coverage 80, 40, 20, 15, 10 meters. Panel metering switch-selected, grid current, plate current, high voltage and relative power output for ease of loading. Weight is approx 140 lbs packed in a box strapped to a small pallet.
