Philips E80CC
Product Description
Philips E80CC - Gold pin, made in the Philips factory in Holland, branded "SQ" for Special Quality. Incredible air and detail, smooth mids, holographic soundstage. For more info on Philips Holland, click here. These are getting hard to find, but we've got decent stocks available now.
The E80CC has slightly different operating parameters than a normal 12AU7, which can affect the way your gear operates. Some folks use the E80CC as a replacement for the 12AU7, but consult your equipment's manufacturer before proceeding as some circuits may not be compatible. Also, the tube is about twice as tall as a regular 12AU7, so make sure you have enough space in your equipment.
Platinum grade - The best of the best. Lowest noise and microphony with the tightest triode balance we have available. This is typically 10% or tighter, but may be higher depending on available stock.
Gold grade - Low noise and microphonics with a triode balance typically between 15% and 20%, but may be higher depending on available stock.
Driver grade - Lowest noise but not the lowest in microphony. Triode balance will be similar to Gold grade.
This grade is only suitable for use in the driver stage of an amplifier, or the output/buffer stage of a DAC or CD Player.
If you have a preamp or phonostage, you need at least Gold grade.

Warranty Information
Vacuum tubes are warranted for 90 days against defects, except in cases of abuse, and replaced with like-item only.
- Tubes being sent in for warranty must have a return authorization number from Upscale Audio. This RA number must be written on the outside of the box. Please also include a note in the box that has your name and telephone number, and please explain the issues with the tube. If this information is missing it will delay the shipment of your replacement tube.
- Vacuum tubes being sent to Upscale Audio for warranty replacement must be shipped in a box with appropriate packaging to keep them from being damaged. Vacuum tubes returned to Upscale Audio using inadequate packing will have a voided warranty and will be refused at the customer's expense.
Exceptions to our warranty policy are as follows:
- Upscale Audio reserves the right to refuse warranty at our disgretion based on the equipment being re-tubed. You will be notified of any change prior to your order being processed.
- Using a tube in an application in which it was not meant to be used. If your amp calls for a 6550, and you decide you want to plug in a 6V6GT, Upscale Audio is not liable if the tube fails, and will not honor any warranty in such a situation.
Upscale Audio is not liable for any damage or injury caused by the improper use of its tubes or the use of an incorrect/incompatible tube type. If you are unsure of what tube or tubes your equipment uses, consult the manufacturer before making a purchase. Using an incompatible tube type may cause severe damage to your equipment and will void your tube's warranty.
vacuum tube returns for refund:
Vacuum tubes are electronic parts and are not refundable under any circumstances.
