The upright Windtunnel Hoover machines are typically bagless, and they store dust onboard. A detachable container allows the user to empty it after each use or as often as needed. Bagless vacuums contain an air filtering system that purifies the air. They are preferred by consumers who are concerned about allergies or other health conditions.

Vacuum cleaners come with several different kinds of filters depending on the model. How often you need to change the filter depends on how often you use the vacuum. In general, the guidelines are:. To find a part or accessory that corresponds to your current machine, locate the dataplate. It may be on the bottom or backside of your vacuum cleaner, depending on the model.

In addition to the heavy-duty chassis, anti-resonance measures include isolation of the tubes and transformers from the chassis with elastomers In order to reduce tube microphonics and transformer vibration. I had originally planned to do a good bit of tube-rolling for this review, but circumstances dictated differently. This review sequence was unusually lengthy, being interrupted by a four-month hiatus caused by my relocation from California to Chicago.

Output: New production Chinese Jim Ricketts also sent a note with several suggestions, which I am including here for reference by interested tube rollers". Since tube tastes are subjective, any high-quality 12AX7 type that an owner prefers would work well and provide that last bit of fine tuning. The Chinese tube is well made in a ISO factory [which indicates stringent quality control standards] and provides excellent sound.

Just to verify my assumption that these amplifiers would match the typical WAVAC sensitivity to tube differences, I did make a couple of brief substitutions with recent-production 12AX7s I had on hand. The differences were indeed clear, but neither substitute rivaled the impeccable tonal balance and transparency of the original.

Review Conditions In the course of several months of listening, these amplifiers were matched with an impressive array of equipment, both upstream and downstream.

The amps performed impeccably with all of them. All three are fairly efficient designs with around 90dB sensitivity. These are SET amplifiers for those who, like me, are generally not big fans of horn-loaded loudspeakers. The Sound Of The MDm To cut to the chase and, I suppose, give away the punch line , the sound of these amplifiers is virtually flawless.

From the left-brain, audio-checklist viewpoint, the only reservations I have are in ultimate power output and ultimate bass performance. As I suggested earlier, their ability to drive reasonably efficient loudspeakers is hardly deficient unless judged against much higher-powered designs.
