Will I need a phono preamp with this unit to hook up my turntable?

This unit has a tube preamplifier, and a solid state amplifier. However, it doesn’t have a built in phono stage (phono preamplifier). Unless your phono has a built in preamp (like an Audio Technica LP120 or similar), you will need a phono preamp if you want to play your vinyl. Phono preamps are fairly inexpensive in the quality range of this unit, so send Amazon another $20 and get your preamp. Don’t worry about Moving Coil (MC) or Moving Magnet (MM) cartridges. If you use an MC cartridge, you probably aren’t going to buy this amplifier.

Do the “blutubes” have blue leds in them? i really want a retro look and am trying to avoid any rgb. thanks!

FYI: Most power amplifier vacuum tubes have a blue glow/hue of some kind. EL34 and 84 tend to contain this with the anode plate structure but is still present around the inside of the glass envelope. 6L6s and 6550s tend to have more of this glow around the glass. The orange glow some people are talking about is the heater filament and has the look of an Edison bulb but only a small part of this is visible as it is contained with the in internal structure of the vacuum tube assembly. This is much easier to see when the room is dark.

what class is the output amplifier?

I needed to contact Rockville and I got this information from them - Rockville BluTube is a Class AB amplifier and uses 6N1 and 6P1J vacuum tubes.

What size is the headphone jack?

I think 3.5 TRS means 3.5mm, which is the standard consumer size of 1/8 inch, used on most cell phones (except newer iPhones, stupid Apple) and portable music players.
