THIS SALE IS FOR A REALISTIC 6CA7 RADIO VACUUM TUBE. IT WAS TESTED ON MY TV-7B/U TUBE TESTER WITH A GOOD READING OF 45. THE MINIMUM GOOD READING IS 30. 

I DO COMBINE SHIPMENTS TO TRY TO REDUCE THE BUYER'S SHIPPING COST. IF YOU BUY TUBES ON 7 DAY AUCTIONS, ALLOW ME TIME TO GET THE TUBES PACKAGED, WEIGHED AND THE SHIPPING COST DETERMINED. I WILL SEND AN INVOICE WITH THE COMBINED SHIPPING SHOWN. ON "BUY IT NOW" SALES, GO AHEAD AND PAY AT THE TIME OF PURCHASE. I WILL THEN COMBINE THE SHIPMENT, DETERMINE THE SHIPPING COST, AND THEN REFUND THE EXCESS AMOUNT YOU PAID. 

I ACCEPT RETURNS IF SENT BACK WITHIN 30 DAYS OF ARRIVAL. THEY MUST HAVE MY TEST RESULTS ON THE TUBES.
