12SG7 RF/IF Pentode tube. Russian 12K4. Vintage 1965Russians made an excellent 12SG7 (That's a 6SG7 12V version) copy and named it 12K4. I happened to acquire some from sources in Russia that ran out of mil biz. The tubes were manufactured in 1965 and had been kept as spares for RF transmitting equipment. All I stock are NOS. Some are labeled as being rechecked in year 1974, see image above. A friend of mine tested several random tubes from the batch I stock, all clones tested strong. The tubes are nice cosmetically as well as electrically. They are metal shielded and need an octal socket. Good for collectors, too.I will combine multiple items for shipping. Please request the total after you are through bidding, I'll then issue you the invoice for payment. You will be asked to pay actual shipping. Tracking is optional and runs $3 per package. There will be individual tracking numbers issued for multiple packages if I have to split large order into 2000 gram segments. It is sometimes cheaper shipping parts as several packages because of silly Lithuanian Post pricing policy.Please allow reasonable time for your order to get to you. We are humans and sometimes make mistakes. I am open to solving any problems should they arise before you post a rough feedback on eBay or escalate a claim.
