If you like sound of Telefunken's smooth plates ECC83 12AX7, you'll like these too, because they are (almost) exact copy. The only differences are in thickness of halo getter and in "staples" which are facing each other.
This is great sub 12AX7 / ECC83 tube for your Marshall, VOX, Ampeg, Carvin, Hiwatt, Fender , ...
We have few 100 pcs boxes of these tubes and we had enough time last few months to carefully measure them on our calibrated Metrix and Tesla tube testers for plate currents and Hickok for transconductance and for microphonics in amplifier..
You can find them rebranded Telefunken, Philips and Siemens, because all three factories have contracts with EI. These are pre war tubes, with exceptional quality, made with 1st class materials, because of that many of them have been rebranded like long life premium versions E83CC and sold by Siemens and Philips in their boxes.
You can also find them relabeled Telefunken with diamond mark on the bottom last few years! Diamond bottom mark is done on laser machine, and if you want to avoid that and to be sure that you are buying genuine Telefunken ECC83 12AX7, just take a look at getter and how staples are faced. Diamond bottom is not proof any more ...

Great hose
Style: Regular, Size: 150 FT
I love these hoses. Length:I have a 50’ for the front yard and 150’ hose for the backyard. Nozzle is perfect for watering flowers, garden or great for washing the car. Flexible: Lightweight and so easy to move around. Turn off the water at the house and let it drain out the nozzle. Doesn’t take long to drain and return to original length. Durability is excellent. Connectivity is so easy.

Great product until it split
We bought the pocket hose 100’ copperhead expandable garden hose through Amazon from Bulbhead April 2025. We love the fact that it is light, retracts, doesn’t kink and came with a versatile nozzle. However, 13 months later, the hose split overnight, leaking an unknown amount of water to the street and eliminating water pressure in our house. Once we found the leak, we contacted the company. We were told there was a 30 day warranty and that our product was no longer covered. I’m not sure what product would break down in 30 days! I was asked if I could be compensated at all and they said no, there are discounts on the website. I will never buy this product through this company again as their customer service is lacking. Nothing was offered as a personal discount for their defective product.

reliable filters at a great price
Pattern Name: 16x20x1, Style: Merv 8
I've been using these Amazon Basics air filters for a while now, and they've been a great value. They fit perfectly, are easy to install, and do a good job of trapping dust, pollen, and other airborne particles.
Since switching to these filters, I've noticed less dust around the house and my HVAC system seems to run efficiently. The MERV 8 rating provides solid everyday filtration without restricting airflow.

Amazon Basics MERV 11 Filters: Solid Performance Without the Premium Price

Amazon Basics MERV 11 Filters: Solid Performance Without the Premium Price
I’ve been using these Amazon Basics 20x20x1 MERV 11 filters in my home HVAC system, and overall they’ve been a very dependable option for routine filter changes. I like buying them in a 6-pack because it takes the hassle out of remembering to reorder every couple of months, and the per-filter cost is noticeably lower than the big-name brands at the hardware store.
Installation is straightforward. The actual size fits my return slot properly with no bending or forcing, and airflow has remained strong. With MERV 11, these strike a nice balance for my setup — noticeably better dust and pollen capture than basic MERV 5 or 8 filters, but without putting obvious strain on the system. After about a month of use, the filters clearly show they’re doing their job, collecting a visible layer of dust and fine debris.
A few things to keep in mind. The cardboard frame isn’t as rigid as some premium filters, and they’re a bit thinner than brands like Filtrete. They’ve held up fine for me during normal use, but I wouldn’t try to stretch them much past the recommended replacement interval. Also, if you have an older or low-powered HVAC system, MERV 11 may be more filtration than you need — in that case, a lower MERV option might make more sense.
Bottom line: These Amazon Basics MERV 11 filters are a practical, budget-friendly choice that deliver solid filtration and good airflow for regular HVAC maintenance, as long as you stick to timely replacements and don’t expect premium-brand rigidity.
