These are NOS/NIB mixed brand tube set which fits Hallicrafters S38C and D receivers but not the 1946 S38. For S38A/B, please check my other listings. The tube numbers are 12SA7, 12SG7,12SQ7, 35Z5GT and 50L6GT. Check your tube layout before you buy.  Unless you have tube shields, these radios require some metal 12SA7, 12SG7 and 12SQ7 tubes to eliminate the shields. Shields are used to eliminate the possibility of harmonic feedback sometimes with glass tubes. 35Z5GT (rectifier) and 50L6GT (power output) tubes are always glass. Tubes have been tested for new performance. I will properly pack for safe shipment and pay USPS shipping with tracking number in the US. Same business day shipping. International shipping through US Postal Service International at actual postage cost and actual selling price on customs forms. 11 ounces packed weight for international shipping.
