A bias tape binding calculator helps crafters and designers determine the amount of fabric needed to create bias tape for sewing projects. This tool simplifies the process, ensuring you have the precise amount of fabric for your project.FormulaThe formula to calculate the square inches of fabric required is:Square Inches of Fabric (SQI) = Length of Bias Tape (LOB) × Width of Bias Tape (WOB)How to UseMeasure Length and Width: Determine the total length and desired width of your bias tape.Input Values: Enter these values into the calculator.Press Calculate: Click the "Calculate" button to see the fabric area needed in square inches.ExampleIf you need 120 inches of bias tape that is 2 inches wide, the calculation is:Square Inches of Fabric = 120 × 2 = 240 square inches.FAQsWhat is bias tape?Bias tape is a strip of fabric cut on the bias (diagonal to the fabric weave) for flexibility and stretch, often used to bind edges.Why is bias tape cut on the bias?Cutting on the bias gives the tape more stretch and flexibility, making it easier to handle curved edges.What is the standard width of bias tape?Common widths range from 1/4 inch to 2 inches, depending on the project.How much fabric do I need for bias tape?Use the calculator to determine the square inches based on the length and width required.Can I make bias tape from scraps?Yes, as long as the scraps can be cut diagonally and joined to achieve the desired length.What fabric is best for bias tape?Lightweight and durable fabrics, such as cotton, are commonly used for bias tape.How do I join bias tape strips?Bias tape strips are joined at an angle to maintain the bias cut and ensure smooth seams.What is double-fold bias tape?Double-fold bias tape is folded and pressed twice to encase raw edges for a clean finish.Is there a formula for continuous bias tape?Yes, continuous bias tape requires fabric dimensions to calculate the required area.Can I make bias tape without a bias tape maker?Yes, you can manually fold and press fabric to create bias tape.Why use bias tape instead of straight-cut strips?Bias tape stretches and curves easily,

Mods suggested.Getting to your questions, if you will check some of my earlier posts on this thread you will note that per the bias calculator, these tubes can be biased at 99 mV in my amp. This equals 70% plate dissipation. The 80 mV setting was were I stopped because of my uncertainty about the 99 mV number. I have not played the amp very much since putting the GT 6L6 Duet Red's in my amp. I intend to do so this weekend. I can say that at the low volume levels I did play, I heard very little difference between a bias setting of 62 mV and 80 mV. I intend to adjust the bias up to the 99 mV level and compare all three bias settings.Regarding why I chose these tubes, I mentioned this in an earlier posting also. I had wanted to try the 7581A tubes because of the clean headroom they are reported to deliver. Because of the difficulting in finding these tubes and the prices thet bring ($150+/pair), I decided to try the GT Red's because of the claim that thet provided more headroom. From what I am reading from others who have posted I am not so sure that this is a totally accurate claim. I'll post my results and conclusions after I have had a chance to explore the different bias settings within the range allowed.As purchased, my HRD came with 6L6WGC tubes and a factory bias of 60 mV. These tubes were. Learn how to calculate bias with our online calculator. Discover how to address gender bias with the gender bias calculator and bias amp calculator.

04-24-2008, 08:29 PM #1 Forum Member Biassing GrooveTube 6L6B I recently purchased a pair of GT 6L6 Duet Red, Gold Series power tubes from Groove Tubes for use in my Fender HRD (1996). The tubes are labeled Fender 6L6B and also Sovtek 5881WXT. I am trying the "reds" because they are suppose to provide a cleaner sound than "standard" 6L6s. I have wanted to try the 7581A but the prices are ridiculous when you can find them. Anyway, I sent an email to Groove Tubes asking for the maximum plate dissipation value so I could use the bias calculator. I received a reply that they are 30 watt tubes along with a suggestion that I set the bias to 60mV using the Fender test point. With the bias set at 62 mV I measured a plate voltage for both V4 and V5 of 424V at pin 3. I also recorded a 1V drop across resistors R62 and R61. Plugging these values into the calculator, along with a maximum plate dissipation of 30W, resulted in a value of 99mV as the maximum bias setting (70% of maximum plate dissipation). I am supprised that the value is this high. I must admit that this is the first time I have used the calculator. The original Fender 6L6WGC (Sovtek 5881WXT) came biassed at 60mV. I bumped this up to 68mV based strickly upon information I picked up reading forums. I have currently set the bias at around 80mV for the new tubes. If

Tell the bias story. Don't worry, and keep doing the math until you get in the neighborhood of 70% max dissipation then tweak to taste (or sound, in this case).

So why would Fender be biasing it so cold? I don't know. Maybe there is something we are missing and someone else can weigh in. Ahoy, Kap'n?

I was beginning to think the bias calculator was correct and that a bias of 99mV for these tubes was correct. Now I'm hearing that maybe the OT can't handle the load. So does that mean you can't go by the bias calculator? 04-25-2008, 04:01 PM #15 Forum Member Re: Biassing GrooveTube 6L6B I dont think the PT is that under-rated. What cdw2000 suggests is to check how hot the PT gets after a half-hour. Keep in mind the 70% rule is for maximum safe dissipation. I usually end up biasing around the 60% mark. You can tweak the final bias by ear to what sounds best to you and the particular 6L6s you have. 04-25-2008, 07:10 PM #16 Forum Member Re: Biassing GrooveTube 6L6B Thanks, JAM. I stopped at about 57% of maximum plate dissipation. I think I will leave it here,. Learn how to calculate bias with our online calculator.
