linear diatonic tube power ampilifier Jason TV Sound Bundle Untested

YS-Audio Audio Experience Symphonies Plus Tube High Def. Linear Preamplifier Used but in excellent condition. There was a problem with the volume potentiometer and it had to be replaced -- it developed scratching. The ALPS volume potentiometer was replaced with a newer, better version as the original developed scratching. The repair was redone with Belden wire - the same wire CBI uses in all their floor pocket wiring. For physical condition I rate this 9 - 9.3 / 10. Comes with (3) 12AX7 preamp tubes and (1) 6x4 Rectifier tube. I will include a spare tube of each if I can find where I put them. I should be able to do so before this sells. No returns but I guarantee it to be fully functional and work without issue. If you do find something wrong, let me know. This preamp was tested before posting. Any questions, please contact me. I will respond quickly and in a professional manner. I have over 3000 feedbacks with only one neutral and zero negative feedback dating back to 2001. Power cord included for USA AC IEC. --Mark

KAEI TAP-1 Portable Desktop Full Balanced Headphone Tube Amp 4900MW + PSU-1 Hifi Linear Power Supply Description:TAP-1 is a high-end headphone amplifier specially designed for audiophiles. It adopts a fully balanced four-channel design and supports 3.5 single-ended/4.4 balanced input and output. Use four American low-power, long-life electronic tubes as tube preamp. It adopts a desktop architecture design promoted by the OP+ discrete rear stage, with a plug-in power of up to 4900mw, and is equipped with a tube off switch function, which can be selected in two tones of normal mode and tube mode. With two flagship op amps MUSES 02, players can also achieve different timbres by changing different op amps.Portable mode: In its battery mode, it can last about 10 hours. The battery capacity is about 5000mah, can support ordinary USB or power bank charging, and supports QC3.0, and PD protocols for fast charging.Desktop mode: Used with an independent linear power supply, it can form a standard desktop amp. Power supply 4 sets of voltage output, external rectified and stabilized voltage directly supplied to the headphone amplifier, completely bypassing the power supply of the headphone amplifier. The dedicated aviation-grade six-core power cable realizes the power supply of the desktop-level op amp up to plus or minus 17V and the earphone discrete drive system, and the potential of this system is played out. If you use it at home or your earphones are difficult to driven, you can purchase the headphone amp.Features:- Four American low-power, long-life electronic tubes as tube preamp (tube can be turned off, dual tone selection)- Air bag shock absorption technology: exclusive electronic tube suspension air shock absorption technology, effectively reducing the microphone effect- The output thrust of plug-in mode is up to 4900MW.

Up for sale is a gently used Linear Tube Audio z10 integrated speaker / headphone amplifier. Please go on the website to check the specs. Make sure that they have enough power for your headphones / speakers. This is the Z10 integrated model. Its MSRP is $4,900, and I also opted for an external power supply unit, also from the LTA brand, which was MSRP $650. Its for US voltages. It comes with the proprietary cable that connects the PSU to the amplifier and the remote, which is an Apple remote that came with this unit, fully calibrated to be compatible with it. In excellent cosmetic condition. It has been sitting on a rack, not moved, since I got it. Tubes have probably 200 hours of usage on them. I took the liberty of upgrading every single stock tube in here (there were MANY stock tubes) with more premium, new old stock, and rarer tubes. Overall, I spent hundreds of dollars simply tube rolling this amp. Its been well taken care of and well loved. I am selling because Im going in a different direction with audio and need something with more juice to power some less efficient speakers. See photos for more info.
