Cool and rare stuff! Made in 1971 by Heerlen/Holland factory of Philips, known as Amperex in the US. These have closed disc getter with 8 dimples. All tubes in stock are from the same batch with identical production code : I66 Δ1I4. Tight matching possible thanks to the large quantity on hand. These come screened for low noise and microphonics.
Quantity in Stock : 75 pcs
Price : Grade A @ US$79,00/ea ; US$162,00/matched pair
Grade B @ US$69,00/ea ; US$142,00/matched pair
Grade A -
The best in the stock. Lowest noise and microphony with the tightest balanced
sections we have available. This is typically 10% or often tighter given the
large volumes of our stock.
Grade B -
Low noise and microphonics with a section balance typically between 15% and 20%,
but may be higher depending on available stock.
Great tubes, excellent sound as described, fast shipping and good packing.
