Tung-Sol 6550 power tubes are an ideal replacement or upgrade for KT88 tubes, offering the same full-bodied tone and professional quality in a readily available tube. This production-model power tube takes more than a few notes from the Sovtek KT88 — Tung-Sol copied the Type 3 triple getter version while constructing it as the uncanny replacement for its inspiration. The result? An incredibly dynamic and open sound that accentuates any genre or playing style. Tung-Sol tubes boast a sturdy construction for long-lasting use without the worry of cracks or defects — in other words, they are fully prepared for the bumpy roads and countless shows ahead of them. Upgrade all your heads and combos with Tung-Sol 6550 Power Tubes!

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
