General Radio Type 1560-P40 Preamplifier & Microphone Tip, Bonus GenRad Mic, GR
General Radio Type 1560-P40 Preamplifier& Microphone Tip For sale- a General Radio Type 1560-P40 Preamplifier and Microphone Tip. I guess that is an apt description. I think the 1560-P40 is just the long cylindrical part and the actual microphone plugs onto the end opposite the XLR connection. BONUS! I have four preamps with microphone tips installed. Plus an additional four microphone tips, so I will include an extra tip at no extra charge. Four of each are pictured. Price is for one and one. I don’t see what I would consider to be a model number on the microphone tip anywhere. There are numbers but I think they are serial numbers rather than model numbers. And in fact they may not be a microphone at all. If that is the case you have my apologies. But they certainly look like microphones. And GenRad or GR as they are often referred to ... moredoes produce microphones as well as acoustic test instruments. So it isn’t much of a stretch to call them what I think(as opposed to what I know) they are. None of the microphones has been tested. And NO warranty is offered. However. IF you pay the asking price and find it has a problem you cannot live with within 14 days of receipt you may return it. Returns are ONLY allowed on Buy It Now Purchases. Accepted Best Offers are strictly an as is sale. No returns allowed. Return would be for a refund of the purchase price. Not including shipping costs. Just so that we are clear on that. This is an item that has not been thoroughly tested. As such it may work fine or it may have problems. So any purchase entails a certain degree of risk. If you Buy It Now your risk is limited to the shipping costs both ways. If you submit an offer you do so knowing that you cannot return it. In either case it is up to you to decide whether the risk level is acceptable to you. And if not you need to pass on this particular item. If you pay the asking price I can probably throw in an XLR cable. But I can’t guarantee you what shape it will be in. Please check out my other listings for more interesting

GENERAL RADIO 1565-B SOUND LEVEL METER & 1567 CALIBRATOR Genrad gr as-is
Sound Level Meter& Calibrator These devices are both functioning. But have not been calibrated in decades. I do not know if they are functioning%100 properly. Due to my inability to fully test them. These items are being sold as-is, no returns accepted. The Calibration unit makes steady noise when powered on. It's not very loud at arms length. But is audible. The SPL meter responds differently to sound based on the DB range setting. In a manner that you would expect it to: higher DB settings make the needle respond less to the same input. Weighting seems to be working- I don't know how accurate it is. But it is functioning, with different weight settings slowing the needle down, averaging the reading out. These devices both run on 9v batteries. Batteries are not included. Free Shipping
